Morcalavin is an enemy encountered in Heretic II. He is the main antagonist of the game and serves as the boss of the Cloud Fortress.


Morcalavin is a Seraph who was trying to perfect the Ritual of Ascension that would make him immortal. Unfortunately, whilst performing the ritual, he used a false Tome of Power (the real one belonging to Corvus). Although making him immortal, it also turned him insane.. Through his insanity, he cast a plague across the world of Parthoris.


Morcalavin can not be killed, but if the false Tome of Power can be replaced with the real one it is likely to cure him of his insanity and hopefully make him stop spreading the plague.
