Eknodine
The Eknodine were a species of aliens that took over the bodies of elderly humans in a dream created by the Dream Lord.
Biology
The Eknodine appeared as aliens that could live inside human hosts thereby extending the life of the host. Most of the body of the Eknodine couldn’t be seen except for a green eyestalk which could be extended from the host’s mouth. This eye could spray out a green cloud when attacking which could turn humans into dust.
