Daemons

Daemons (DAY-MON) are orphan fragments of what were once Sidereal Host. The other parts of the The Sidereal Fae  were destroyed, leaving unguided pieces similar in concept to independent and self sustaining blood cells. Daemons do not have the ability to reconstitute their higher selves.
Daemon types: Kobolds: These Daemons have made a pact with the world to become part of it. They use Alchemical magics and something unique to them to forge a proper soul and join the cycles of the world.
Overlords: The Overlords existed on the isle of Kuan and the the Shards after the fall of the Demon Age. The Overlords worked with a fragment of the Thing from Outside that radiates strange energies and cracked fissures in the planar structure of the mortal world. Overlords are invulnerable to normal material injury and create Mirror realm pockets for short periods of time.
Mindworms: Once the means of control over slaves of a Sidereal Master the worms individually are mindless and no longer impose the Master's will. They are driven to infect, multiply and spread. As the colony becomes aware this is modified by dominion and infiltration. Mindworm tend to burn through hosts as they don't understand host bodies unless the colony is large enough.
