Ren Miruu

The Ren Miruu were an advance race that inhabited the galaxy long ago. They were worried about the younger races would eventually causing a "class-30 singularity event". While it is unclear what a "class-30 singularity event" is, it believed the Ren Miruu discovered type of technology that would trigger an event that could destabilize the fabric of the universe. To prevent this, the Ren Miruu develop an advance Ai called the Contingency. After its creation they committed suicide probably seeing no need to watch over the younger races anymore.
