Vultaumar Prime

The shattered remnants of the Vultaum homeworld reveal that it underwent a massive extinction event 12 million years ago, caused by the detonation of some kind of antimatter device. From the ruins that remain on the …'s surface, we have learned that Vultaum society experienced a radical ideological shift a century before their extinction.

Their new philosophy posited that the entire universe was an artificial reality which all sapient beings had been unwittingly plugged into for the amusement of some higher power. The Vultaum undertook increasingly radical attempts to forcefully "disconnect" themselves from this simulation, most of which involved mass suicide.

They finally concluded that only the simultaneous disconnection of billions of individuals would destabilize the system enough to grant them freedom. At an agreed upon hour, Vultaum everywhere killed themselves by any means available. Those who refused to take part in this mass suicide were too few to repopulate the species, and so the Vultaum faded into obscurity and eventual extinction.
