The official Borderlands 4 game info page introduces Terminus Range as a punishing ice frontier overseen by Vile Lictor. Here’s everything Gearbox has shared so far.
The towering peaks of Terminus Range are as unsympathetic as they are cold. Secrets both ancient and man-made hide beneath blinding snowstorms. The Augers mine Ordonite under Vile Lictor's terrifying gaze and cling to warmth inside their carved halls.

As you traverse Kairos, keep an eye out for Points of Interest that you can claim for the Crimson Resistance. Clearing enemies lets you convert safe houses into fast-travel nodes or relaunch Order comm balloons to scout and track Vault Key fragments.
The campaign is fully scalable for four-player online co-op with instanced loot, level synchronisation, and two-player splitscreen on PlayStation 5 and Xbox Series X|S.
Remember that cold-resistant loadouts and coordinated crowd control will matter once Gearbox releases the full mission flow for this region.
Detailed boss mechanics and loot tables for Vile Lictor will arrive through official patch notes and DLC spotlights. Until Gearbox publishes those, avoid unverified guides that invent drop rates or waypoint coordinates.
