Incarni

When a mortal shows exceptional power and promise by a Daimos’s standards, they may become touched by their power, becoming a physical and magical extension of the Daimos’s nature. These entities are known as Dai Incarni, or simply Incarni, and they abound in the domains of each Daimos.
  Incarni are no longer mortal, their existence instead becoming tied to that of the Daimos who corrupted them. They can still be killed, though mundane weapons harm them little. Their appearance changes to match their Daimos’s nature: sometimes imposing, sometimes malformed, sometimes beautiful, and sometimes terrifying but always monstrous and inhuman. Each Daimos has hundreds of Incarni in their service, willing vessels of the Depths sent out to corrupt mortals into service of their Daimos or to lead the terrifying armies of the Hollowdepths against the surface-dwellers.
