Z'traa (OU)

The Vrai homeworld, or Z'traa, in the White Nebula, is where the Vrai originated from.

The constant genetic experiments of the Vrai proved to be the end of this planet, when its entire population was wiped out by an experimental bioweapon that was set off by a rogue Vrai, Xeno.

50,000 years later, the planet was once again inhabitable, until Blackout destroyed it.
