SAMI AND THE COLLAPSALS: THE COMING THREAT

If you were anywhere near Arknights community spaces after the Version 1.5 preview program, you saw it happen. A new snowy forest zone gets announced, a Sarkaz archer who talks about Sami shows up, and suddenly every player with two thousand hours in the original Arknights starts typing words like Collapsal, Crazelyseon, and Amma in full caps. To an Endfield-only player, that reaction looks completely disproportionate. It is not.

The short version: the frozen north of Terra hides the closest thing the Arknights setting has to a cosmic horror faction, and there is a plausible chain of evidence connecting that horror to Talos-II. Whether Hypergryph intends to pay it off in Endfield or keep it as atmosphere, understanding it now means every name drop in the Snowy Forest will land the way it is supposed to.

This primer assumes you never touched the original game. No reading order, no prior knowledge required. We will define what Sami actually is, explain why the Collapsals scare people who fight dragons for a living, walk through how any of it could plausibly exist on a different planet, and then look at what 1.5 is actually teasing.

TL;DR - Key Points

• Collapsals are info-hazard entities: knowing about them makes them stronger, and thinking about them too hard can corrupt you into one.
• Their corruption warps reality itself: perception breaks, numbers stop working, machinery gets taken over, and symptoms include black fluid that cameras cannot record.
• Most Terrans have never heard of them because the nations bordering the north actively suppress information. What leaks through is just “demons from the wastes”.
• Sami, the region, is also Sami, a living god: the tundra is the body of a Feranmut, which explains the living trees and the animism.
• Collapsals came from somewhere else entirely. They were never native to Terra; they arrived through a gate.
• Amma pushed Crazelyseon through the Cosmic Gate at the cost of its own life, and Amma has since been confirmed on Talos-II. That is the whole theory in one sentence.
• 1.5’s Snowy Forest fits Sami thematics exactly: runes, mist, bewitchment, witchcraft enemies, and a story-collecting Sami guide named Typhoeus.
• Nothing is confirmed. The smart money says this patch is setup, not payoff, and Terra’s arcs probably resolve in the original game.

Why a Snowy Forest Made Veterans Panic

Start with the reaction itself, because the scale of it is data. Version 1.5’s reveal includes a new area outside Yinglung Pass, some Ents, a boss called Gloomwald’s Rage, and a six-star operator whose tagline is “Everything is a gift from Sami.” Read coldly, that is standard fantasy expansion content: winter zone, forest monsters, nature archer.

Read with original Arknights context, almost every element doubles as a reference. Sami is not a random snow biome; it is the setting of one of the original game’s most acclaimed and unsettling storylines. A misty forest covered in runes that messes with your head describes Sami’s supernatural interior almost word for word. And the community spent years watching that storyline escalate from “spooky woods” to “reality-ending entities leaking through a hole in the world.”

So when those players saw Endfield open a bewitched snowy region and staff it with a character from Sami, they did what veterans do: they started checking whether the horror followed the settlers through the gate. The rest of this post is the checklist they are working from.

What Sami Actually Is

On paper, Sami is a region on Terra’s northern edge, loosely analogous to Scandinavia and the far north in our world. But even the surface description is unusual. Sami is not a unified country. It is a scatter of towns and settlements across cold tundra, with no central state, and the residents practice a druidic nature worship built around trees that are alive and mobile. Not metaphorically alive. Walking, willful trees, some of them enormous.

The culture splits into two related peoples speaking two distinct languages, which the original game models on real-world northern cultures: one half draws heavily from Finnish tradition, the other from Old Norse and Scandinavian roots. Hypergryph did its homework here, down to names and vocabulary, which is part of why the fanbase treats the region with unusual respect.

Two more facts matter for our purposes:

• Sami is unexplored on purpose. Deeper Sami is dangerous in ways nobody has fully mapped. Expeditions go missing. Instruments lie. One famous operator found her world-ending fire sword lying in Sami’s interior, and organizations like Rhine Lab keep funding expeditions anyway, chasing answers.
• Sami is a person. This is the part that reframes everything else: the region is the body of a Feranmut, a gargantuan living entity called Sami the All Father. We covered Feranmuts in detail in our Sui Proxies explainer, but the relevant summary is that these are mountain-sized near-immortal beings whose bodies become geography when they die. Sami never died. The tundra, the trees, the animism, all of it reads as the will of something that is still there.

That last point does quiet work later in this argument. If Sami is an entity rather than a place, then Sami is not bound to Terra the way a country is. Entities can move.

The Collapsals, Explained Without Getting Hurt

Now the reason for the yelling.

The Collapsals are entities that entered Terra long ago through what lore calls the Northern Gate, in the planet’s far north. They are best understood as extradimensional: not animals, not a civilization, not malice of any kind. They are closer to a force of nature that hates the fact that you exist as an observer. Community comparisons to SCP-style anomalies are accurate and widespread.

Their properties, as established across the original game’s Sami content:

The corruption details are genuinely unpleasant, which is part of the faction’s appeal. Documented signs include victims found hollowed out, black liquid seeping from everywhere it should not (fluid that cameras cannot record), and worse. There is no malice in any of it. The Collapsals are simply what they are, which is precisely what makes them scarier than any villain in the setting.

Because knowledge feeds them, Terran nations handle Collapsals the way you would handle a memetic hazard: compartmentalize. Only select warrior orders are permitted to know they exist and fight them. Everyone else knows the northern wastes hold “demons” and leaves it there. The countries that live with this problem, Sami, Ursus, and Yan, each guard their own stretch of border because the front is too vast for cooperation to help. Yan in particular has always been the least prepared, busy with its own sealed-god problem, a decision that backfired badly when the Great Hunt against Sui weaponized Collapsal energy and widened the incursions.

Rule one of the Collapsals is that the less you know about them, the better off you are. Rule two, learned the hard way, is that ignorance will not save you either.

Collapsal Paradigms

When a region falls deeply under their influence, the distortion crystallizes into named phenomena the original game calls Paradigms. A few recorded examples give you the flavor:

This is the texture OG players associate with the far north: not difficulty spikes, but the rules of the game quietly refusing to apply. Keep that in mind when a certain new Endfield region advertises itself as a mist-bound zone where the environment fights you.

How Any of This Reaches Talos-II

Here is the question that makes the theory interesting instead of just nostalgic. The Collapsals are a Terra problem, and Endfield takes place on Talos-II, reached by migration through a gate that has since closed. So how would they follow?

Three links in the chain, each individually canon:

First, the Collapsals were never native to Terra. They arrived through a gate. That matters because it establishes them as travelers between places rather than a regional species. Anything that crossed once can cross again.

Second, the Cosmic Gate sits in Terra’s far north, in Sami’s neighborhood. This is the same gateway Terran civilization used to migrate to Talos-II roughly 152 years ago before it closed during the First Aggeloi War, a history we traced in our Foundation and Exiles breakdown. The single most important event in Sami’s modern lore happened at that gate: the Beast Lord Amma sacrificed itself to force the Collapsal Crazelyseon through it. The act saved Terra from one of the worst of them and hurled it somewhere unknown. Nobody, in fiction or out, has confirmed where it went.

Third, Sami itself has already demonstrated it can cross. The current reveals confirm that Amma ended up on Talos-II, and records indicate at least one of Sami’s colossal walking trees passed through the gate during the migration era, planting a foothold. The floating city of Ses’qa, introduced back in Version 1.3, is physically anchored to a gargantuan tooth of Sami. Sami the entity is present on this moon in a way that predates anything Endfield has done with it.

Put together: an extradimensional predator was last seen going through a door, the door leads to Talos-II, and the god whose territory the door sat in is already here, along with the thing that shoved the predator through. That is why veterans read a rune-covered misty forest and immediately ask what else might have come across.

There is also the softer version of the argument. Talos-II already has its own reality-decay phenomenon in the Blight, driven by overlap with a hostile dimension called the Aetherside, measured on a Depth scale where 0.5 marks peak Blight incidence. In-game scientists have openly theorized a connection between the Blight and Terra’s northern demons since launch. Version 1.4 complicated that by confirming the Aggeloi are crude creations of the Foundation, but nothing has ruled out that the Aetherside and whatever dimension birthed the Collapsals are neighbors, or the same place. Our Feranmut Proxies analysis covers the Depth mechanics if you want the physics side.

The Case For: What 1.5 Is Actually Teasing

Lay the circumstantial case out, item by item:

• The Snowy Forest is described as bewitched. Runes, mist, an atmosphere that fights you. That is a toned-down description of Sami’s interior, where instruments fail and perception bends.
• Witchcraft enemies and a boss named Gloomwald’s Rage. Endfield’s existing factions are technological or Feranmut-derived. A magic-specialist enemy type arriving in a Sami-coded region is a new note for the game to hit.
• Typhoeus herself. A Sarkaz reconvener who travels Sami alone collecting and preserving its stories, debuting in the very patch that opens a supernatural snow zone. Story collectors do not collect stories in places without stories.
• Trial of the Bow sends you hunting special Sami arrows. The challenge event is explicitly framed around Sami craftsmanship, in a region nowhere near Terra’s Sami. Somebody brought those arrows a very long way.
• The tagline. “Everything is a gift from Sami” is written for the exact audience currently losing its mind online. It is a wink, and winks in gacha games tend to foreshadow.

None of this proves Collapsals appear in 1.5. All of it proves Hypergryph knows exactly which memories it is poking.

Where Typhoeus Fits In

Since we are already running her build coverage, it is worth separating what Typhoeus means mechanically from what she means narratively, because the second half explains why she anchors this theory.

Mechanically she is a Nature Striker with a hover kit, and everything practical lives in our Typhoeus build guide: the Signs and Hunting Arrows loop, the Arts Unit weapon situation, Qingbo gearing, and the Nature applicators she wants beside her. Nothing in her kit touches lore. Build her normally.

Narratively, she is dense with references. The community consensus is that she is a Reconvener of Typhon, an original Arknights operator from Sami who fought using arrows crafted from Collapsal shards. Every confirmed Reconvener so far had Oripathy in their original identity, and Typhon had it. Typhoeus shares the hunting background and the greatbow while missing the horn ornaments Typhon inherited from her parents, which fits the pattern of reconvened individuals being reconstructed close to, but not exactly as, their originals. Our pre-reveal reasoning lives in the Sarkaz Dream Traveler breakdown.

Why does that matter for the Collapsal question? Because if Typhoeus carries Typhon’s reconstruction, she may carry fragments of what Typhon knew. A story collector from a region whose stories are suppressed, standing in a bewitched forest on the far side of a dead gate, is either coincidence or the setup line for the scariest arc Endfield has run. Given how carefully this roster’s references have paid off so far, betting on setup feels right.

The Skeptic’s Case, Taken Seriously

Balance matters here, because the strongest counterargument comes from the same threads as the hype and it is good.

Terra’s stories should resolve in Terra’s game. The Collapsals, like the Seaborn and the fates of the Sui siblings, are multi-year arcs that original Arknights players are emotionally invested in concluding. It would be genuinely bad storytelling to resolve them casually in a spinoff, where the answer arrives as a spoiler: “oh, the interdimensional demons? Handled, years ago, nobody you know died.” Hypergryph runs both games and has every incentive to keep the big resolutions in the flagship.

The honest synthesis is this: Endfield can borrow Sami without borrowing the Collapsals’ conclusion. The Snowy Forest can be haunted by Sami’s ambient weirdness, by echoes and remnants, by witchcraft-flavored enemies inspired by the north, all without ever confirming that Crazelyseon landed here. Atmosphere is cheap to import; plot resolution is expensive. Expect the first, hope for the second, believe neither until you see it.

What Would Confirm the Theory

Watch for these signals over the next few patches:

1. Any enemy or dialogue referencing perception distortion, lost time, or impossible geometry in the Snowy Forest. That is Paradigm language.
2. Named drops. The words Collapsal, Crazelyseon, or Amma appearing in quest text or Nexus Files entries would move the theory from inference to canon.
3. Typhoeus’s event dialogue. Trial of the Bow keeps its story playable after the event ends, so there is no rush, but read what she says about the forest. She is the designated lore carrier this patch.
4. Depth anomalies. If the Snowy Forest registers abnormal Aetherside Depth readings compared to neighboring regions, the Blight-and-demons theory gains serious ground.
5. A Sami-aligned future region. Ses’qa floats on Sami’s remains in the far north of Talos-II’s map and has been sitting unvisited since 1.3. That city is the obvious delivery mechanism for any full Collapsal arc.

What This Means for You, By Player Type

• Endfield-only players. You lose nothing by ignoring all of this. The game defines its own terms, and the Snowy Forest works as spooky winter content on its face. Treat this post as subtitles for the reactions in your feed.
• OG Arknights veterans. Manage expectations downward. The references are real and deliberate, but the payoff, if it comes, is probably not this patch. Enjoy the recognition; do not pre-grieve your favorites.
• Pull planners. This lore has no mechanical impact yet. Typhoeus’s value lives or dies on her kit, which we covered separately. Do not pull for a horror story that has not been announced.
• Lore hunters. The Snowy Forest’s Nexus Files entries and Typhoeus’s event dialogue are where any confirmation will land first. Check both before trusting anyone’s theory thread, including ours.

Common Mistakes When Reading the Hype

• Treating “Sami is coming” and “Collapsals are coming” as the same claim. Sami’s presence on Talos-II is already established canon. Collapsal presence is speculation built on top of it.
• Assuming the Blight is confirmed to be Collapsal-related. It is an in-game scientist theory, nothing more, and 1.4 actively complicated it by tying the Aggeloi to the Foundation.
• Believing every namedrop is a promise. Hypergryph seeds references constantly, and most stay references. Ses’qa has floated on Sami’s tooth since 1.3 without the story going anywhere near it.
• Skipping the patch content because “the real stuff comes later.” The bewitched forest, the witchcraft enemies, and Gloomwald’s Rage are the version regardless of what they foreshadow.

Final Read

The veterans panicking about Sami are not overreacting. The Collapsals are the best horror concept in the Arknights setting: an enemy that gets stronger when you talk about it, written with genuine care, and last seen being hurled through the exact door that leads to Endfield’s planet. The evidence that something came across is circumstantial but well-built, and 1.5’s snowy region is dressed head to toe in the iconography.

Still, the realistic read is that Version 1.5 imports atmosphere, not resolution. Sami’s stories arriving on Talos-II through a story-collecting archer is elegant setup either way. Whether the things those stories warn about follow her through the mist is a question for a future patch, probably one that opens the road to Ses’qa.

Play the Snowy Forest when it lands on September 2, read what Typhoeus says carefully, and check back here. We will update this piece the moment anything in game text says the word.

FAQ

What are the Collapsals in Arknights?

The Collapsals are extradimensional entities that entered Terra through a gate in its far north. They warp reality and perception around them, and merely perceiving or thinking about them can corrupt a person into one of them. Because they grow stronger the more people know about them, most Terran nations actively suppress all information about their existence.

Is Sami a country or a creature?

Both readings are true at once. On the surface Sami is a loose collection of towns across a frozen tundra whose residents practice nature worship among living trees. Underneath that, the entire region is the body of a living Feranmut called Sami the All Father, and much of the region’s strange behaviour is that entity’s will.

Are Collapsals on Talos-II?

Not confirmed, but the pieces line up uncomfortably well. The Beast Lord Amma sacrificed itself to shove the Collapsal Crazelyseon through Terra’s Cosmic Gate, and Amma has since been confirmed on Talos-II. If Amma made the crossing, the reasonable assumption is that what it pushed through the gate did too.

What is Crazelyseon in Arknights lore?

Crazelyseon is a named Collapsal from the original Arknights’ Sami storyline. During the events around Expeditioner’s Joklumakar, the Beast Lord Amma forced it through the Cosmic Gate at the cost of its own life. Where it ended up was left unresolved, which is exactly why Endfield’s snowy region has veterans worried.

How did Sami reach Talos-II if it is part of Terra?

Through the Cosmic Gate, the same hyperspace gateway in Terra’s northern icefields that carried Terran civilization to Talos-II roughly 152 years ago. Records indicate at least one of Sami’s walking trees passed through the gate, giving Sami a foothold on Talos-II, and the floating city of Ses’qa is anchored to a gargantuan tooth of Sami.

Is the Blight related to the Collapsals?

They share an aesthetic family but are not confirmed to be the same thing. The Blight is a manifestation of the Aetherside overlapping realspace, while Collapsals entered Terra through a northern gate. In-game scientists have theorized a connection between the Blight and Terra’s demons, but Version 1.4 confirmed the Aggeloi are Foundation creations rather than Collapsals.

Who is Amma in Arknights?

Amma is a Beast Lord associated with Sami’s deep past, appearing in the Expeditioner’s Joklumakar storyline. Amma died pushing the Collapsal Crazelyseon through the Cosmic Gate, an act that removed one threat from Terra while possibly exporting another somewhere else. The reveal naming Amma as present on Talos-II is the detail that reignited Collapsal speculation.

What does Typhoeus have to do with Sami?

Typhoeus is a Sarkaz reconvener who travels Sami collecting and preserving its stories, and her stream tagline, Everything is a gift from Sami, is a direct nod to the original game’s Sami arc. She is widely believed to be connected to Typhon, an operator who fought with arrows crafted from Collapsal shards. Her arrival alongside a bewitched snowy region is suspicious timing.

Will Version 1.5 feature Collapsals in Endfield?

Nothing announced confirms it. Version 1.5 brings the Snowy Forest, Ent enemies, a witchcraft enemy type, and the boss Gloomwald’s Rage, all of which fit Sami thematics without requiring Collapsals. Most likely this patch builds the atmosphere and the story pays the Collapsals off in a later version, if at all.

Do I need to play the original Arknights to follow this?

No. Endfield keeps its plot self-contained and defines its terms in the Nexus Files. Knowing the original game changes recognition rather than comprehension: you will understand why veterans react to certain names, but nothing in Endfield currently requires that background to follow the story.
