Survival was only the beginning.

Alec West and his team have finally found sanctuary within the arcane-protected city of Bastion. But peace never lasts. When a scout patrol vanishes near a mysterious Obelisk-born structure, Bastion’s council calls on Alec’s battle-hardened squad to investigate.

What starts as a rescue turns into a desperate race against time. Buried in the ruins lies a Progenitor-class artifact—a Trial Key capable of rewriting fate itself. And when one of their own is mortally wounded, Alec must lead his team into an otherworldly dungeon known as the Tower of Teeth for a chance at the impossible: resurrection.

But the Obelisk rewards ambition as much as unity. The Iron Sovereignty faction wants the artifact for themselves. The trial is PvP-enabled. And not everyone who enters will leave.
