Alexios

An ancient lich from the Fel'zai desert, Alexios is the true shadow ruler of Valtyr. His existence was made known to you by the incubus Drogar, a devil in service to Asmodeus, Prince of the Nine Hells. Drogar details Alexios' plan to use the Soul Crystal to snuff out all life in Averron in an instant, and urged you to kill him.

The beholder Xanathar later confirmed Alexios plans, and sent you on a mission to gather four vital ingredients necessary to put an end to the lich once and for all.
