ARK Lost Colony: Every New Creature on Arat Prime

 

    ARK: Survival Ascended's Lost Colony expansion released on December 19th, 2025 for $29.99, and per ark.wiki.gg it's "the overall sixth paid canonical Expansion Pack in the ARK franchise." Its setting is Arat Prime, a Gothic necropolis guarded by a Thrall army — but this guide sticks to the creature roster only: the five newly described tames, the full "Unique creatures" list the wiki attaches to the DLC, the three Skill Tree companion forms, and the Gargoyle statues scattered across the map. Where the wiki names a creature without describing what it does, that gap is stated rather than filled in.

 

The Five New Creatures of Arat Prime

 

    Per ark.wiki.gg, Lost Colony's "New powerful creatures include" five specific entries:

 

• Veilwyn — "a small, fox-like companion that can create small, portal-like holes to teleport and grant unique and helpful buffs to the player," which "can later evolve into one of two formidable forms, each unlocking entirely new and potent abilities." Those two evolved forms are named on the wiki as Malwyn and Solwyn (see the roster below).
• Ossidon — "a monstrous, demonic-looking primate of raw endurance and cryogenic elemental might adapted to survive in the frozen wastes of Arat Prime."
• Gloon — "a strange-looking frog-like creature with large translucent eyes that has unusual reactions in nearby creatures, calming some, provoking others."
• Aureliax — "a colossal Chinese-style dragon that is found high above the frozen peaks of Arat Prime," a "master of its duality: warp reality to protect, heal, and levitate allies, or crush enemies with gravity and death."
• Cryolophosaurus — "a theropod that can either spit an unusual liquid-based substance as a torpor-inducing glob or exhale it as a freezing blast of cold air." The wiki's own trivia also flags it as the first creature "originating from a mod to be released in a paid canonical map rather than the other free maps within ASA."

 

    None of these five have documented taming methods, preferred food, or saddle-unlock levels in the source pulled for this article — that level of detail would live on each creature's own dedicated wiki page, which wasn't part of the DLC overview captured here, so those specifics are undocumented rather than guessed.

 

The Full Unique Creature Roster

 

 

    Beyond the five described above, ark.wiki.gg's own "Unique creatures" list for Lost Colony names 11 entries total: Alpha Ossidon, Aureliax, Cryolophosaurus, Gigadesmodus, Gloon, Malwyn, Neophyte, Ossidon, Solwyn, Thrall, and Veilwyn — the five already covered plus six more names (11 − 5 = 6).

 

    Of those six, Malwyn and Solwyn are confirmed as Veilwyn's two evolved forms flagged above, though the wiki doesn't currently describe what distinguishes one from the other beyond each unlocking "entirely new and potent abilities." Alpha Ossidon and Gigadesmodus appear only as names on this list — the source gives no description, stats, or role for either, so this guide leaves both undocumented rather than guessing whether they're boss variants, tamable alphas, or something else entirely. Thrall and Neophyte also sit on this same roster line, but the source gives no creature description for either here — they appear only as names on Lost Colony's creature list, so this guide doesn't characterize them beyond that.

 

Skill Tree Companion Forms

 

 

    Lost Colony's new Skill Tree system is described as letting a survivor "earn points by achieving Milestones and invest them in skills across distinct trees, allowing for deep specialization as a master of creatures, a seasoned explorer, or a resourceful survivor." Under that system, the wiki lists three "Skill Tree Creatures" separately from the tamed roster above: a Cat, granted by the Feline Form Skill; a Spirit Direwolf, granted by the Spirit Beasts Skill; and a Helper Wisp, granted by the Wisp of Industry Skill. These are skill-granted summons, not creatures you hunt or tame in the world — and the source doesn't document what each summon actually does mechanically beyond the skill name itself, so this guide doesn't invent buffs, durations, or stats for them.

 

Gargoyles: The Frozen Guardians of Arat Prime

 

 

    Gargoyles are a separate hazard, not additional tames. Per the wiki: they "are creatures who have been frozen in time by the statue and are awakened when alerted by the Red Colony. None of the creatures listed here are tamable due to the Lost effect." Counting the wiki's own Gargoyle list gives 36 creature types — mostly existing ARK species reused as frozen statues, including Argentavis, Baryonyx, Carnotaurus, Dire Bear, Managarmr, Megatherium, Rex, Rock Drake, Spino, Woolly Rhino, and Yutyrannus, among others.

 

    Three names cross over with the creature rosters above: Malwyn, Ossidon, and Cryolophosaurus each appear on the Gargoyle list too. That means the wiki documents a frozen, non-tamable Gargoyle version of those same three creatures as a separate encounter from the tamable version described earlier in this article. The source doesn't explain the mechanical difference between a Gargoyle Ossidon and a tamable Ossidon beyond stating the Gargoyle can't be tamed, so this guide doesn't speculate further on what else differs between them.

 

Lost Colony's five headline tames — Veilwyn, Ossidon, Gloon, Aureliax, and Cryolophosaurus — are the only new creatures with any confirmed abilities in the source used here; taming methods and saddle levels for them aren't documented yet, so budget scouting time before committing resources to a specific one. And don't mistake a Gargoyle sighting for a tame opportunity: the wiki is explicit that none of the 36 Gargoyle types are tamable, "due to the Lost effect," including the frozen versions of Malwyn, Ossidon, and Cryolophosaurus — treat any statue as a fight, not a trap-and-feed target.

 

Running your own ARK server

 

    Sorting out which Lost Colony name is a new tame, which is a skill-granted summon, and which is a hostile Gargoyle statue matters more when you're not racing a crowded public server to the same Veilwyn spawn or pulling stray aggro onto someone else's trap. On your own ARK server, your tribe can scout Arat Prime's frozen city at its own pace, and the map runs on the same GameUserSettings.ini/Game.ini taming and breeding rates as any other ARK map — whatever multipliers your tribe already uses carry straight over to the new roster with no extra setup.

Conclusion

 

    Lost Colony's creature roster, per ark.wiki.gg: five newly described tames (Veilwyn, Ossidon, Gloon, Aureliax, Cryolophosaurus), an 11-entry "Unique creatures" list that adds Alpha Ossidon, Gigadesmodus, Malwyn, Solwyn, Neophyte, and Thrall to those five, three Skill Tree summon forms (Cat, Spirit Direwolf, Helper Wisp), and 36 Gargoyle creature types that reuse familiar ARK species as frozen, non-tamable statues — three of which (Malwyn, Ossidon, Cryolophosaurus) also appear on the creature rosters above as separate encounters. What the source doesn't give — taming methods, preferred food, saddle levels, and what mechanically separates a Gargoyle version of a creature from its tamable counterpart — is left undocumented here rather than guessed.
