Dreen

The Dreen were a parasitic infectious life form that existed After Exodus and possibly before (little activity during BE). Dreen were a hive-mind species controlled by the Thinking Dead, a final stage humanoid parasite that can only exist independently, meaning only one can exist at any given point. The origin of Dreen is unknown, it is speculated that they were cultivated as biological warfare.

Dreen can go through a number of stages, from feral (infecting hosts and attacking masses) to interrelated (controlled by a Thinking Mind), and finally to interstellar (controlling spacecraft or technology built by the host, to infect more life forms).

Dreen do not affiliate with anyone, nor can they be controlled by any known method.
