Bokor

The Bokor are a sapient species of microscopic parasites which spread as a disease, first killing their hosts then reanimating and assuming control of their dead bodies.

The Bokor operate under a unified hive mind and retain the memories and knowledge of all hosts ever assimilated for over 50,000 years. Once they control a host's body, they exhale spores from the host's mouth to infect other nearby creatures. Strong electrical charges can kill the Bokor.

Under normal circumstances, the Bokor can only assume control of a host's body after the host is dead. However, should they infect a body which isn't alive in the traditional sense, such as a Celestial Avatar, they can control it immediately.
