Ren Miruu

The Ren-Miruu were an ancient, highly advanced space-faring empire of unknown origin. The empire is responsible for the creation of The Contingency, an artificial intelligence of colossal proportions constructed in order to halt the push of a "Class-30 Singularity Event", something which, in their eyes, could cause the end of the universe as they knew it. For unknown reasons, the entire race collectively commited suicide as soon as they completed the project.

Their nature is unknown. Dialogue with The Contingency it self seems to suggest that the Ren-Miruu were either natural or Hive-Minded.
