After taking a minute to examine the leader of the group of undead, Marcus was almost certain that they were a powerful undead known as a lich.
He had come across a few entries about such beings within his reading at the adventurers guild and Borealia's royal archive when searching for information on ghost kings and fonts of death which he needed in order to achieve his evolution.
'Thin pale skin that is translucent, hair that is bone white, eyes that are red like blood, and an aura of oppressive death. Four characteristics that a lich is said to possess.' Marcus thought while looking down upon the mastermind behind the resort and his undead minions.
