An incarnate is an diabolist who has successfully turned their entire party to the service of the void, the reward for such an achievement is to be elevated to an incarnate by Ayneaxian. As an incarnate their body is changed, forever warped by the power of the void, becoming an incarnate is a first step on the path to demon hood, it is as an incarnate that they perform the most horrendous of deeds to fully complete their accession, and becoming the leader of their party of void servants.
As a creature of warped flesh, it is impossible for them to move within populated areas during the day, and even at night they need a cowl and shadow, as such they are not off adventuring. The incarnate will set up a fortified position within underground areas, often sewers or dungeons, using their minions to slowly take over the city and wider areas, in the hope of creating a void touched land.
