So yeah, I've got a CR 16 Mummy Lord very confused to be in a forested faery land in possession of a powerful artifact sacred to the gawd of the dead, who HATES undead in this setting. This Mummy Lord is in the middle of the PC barony, a rival monster kingdom about to invade, rival city states that fear expansion of their kingdom, a soon-to-be awakened cyclops lich in a nearby barony's ruins who will resume world conquest on behalf of his long-dead conquering race, and a supreme fey threat yet to be fully unveiled.
So, ideas where my poor Mummy Lord goes and does? I really wasn't expecting this...
