Enslavers

The Enslavers are creatures that inhabit the Immaterium. They are also known as Psyrens, Krell, Dominators or Puppeteers. Enslavers drift with the currents of the Immaterium, and are drawn to the psychic emanations of other creatures. Once a suitable psyker host is located, the Enslavers form a parasitic mental bond, which over the course of a few days will turn the unfortunate, mind-controlled host into a living warp portal, so that more Enslavers can enter the material universe and find new hosts.

The Enslavers had their most profound impact on the galaxy in a catastrophic event known as The Enslaver Plague. As a result of the tactics employed in the War in Heaven, the Immaterium became greatly destabilized and a rush of Enslavers to the physical universe occurred. The Old Ones were wiped out and life in the galaxy became almost extinct. This included all the living creatures that the C'tan use as food, so the C'tan went into hibernation, along with their Necron armies, to wait for the galaxy to become repopulated.

Appearance
The Enslaver's body consists of a spherical lump trailing tentacles. The Enslavers can change their body color at will, and float up to three meters above the ground.
