Baalites

The Baalites (or Servants of Baal) were a unified league of interstellar species that purged the Milky Way Galaxy in search of artifacts, killing the majority of the human race in the process.

Not much is known about the origins of the Baalites or what species are in league with their purpose, other than they are all interstellar-level beings. They are believed by many to exist to destroy and corrupt. They are the current most dominant species in the Milky Way Galaxy, as known humans number less than their population on Terra during the Information Era.
