Thestus is an NPC in Mortal Shell. Thestus can be found at Fallgrim Tower. Thestus is always hungry for another Glimpse. He can summon or cancel The Mist at will.

Thestus Information:

• If you pay him 1 glimpse, Thestus will summon or cancel The Mist at will. Traveling to another region (such as with the ornate mask) or dying while in the Mist at this point (i.e. while not carrying a Gland) will reset the world state and cancel the Mist.
