Z'traa (OU)

Z'traa was a planet in the White Nebula and the original home of the Vrai species.

The constant genetic experiments performed by 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.

Z'traa's legacy lived on in two other worlds: Neo Z'Traa, a subsequent Vrai colony which was warped out of recognition by Osseron, and New Z'traa, a brand new planet created for the Vrai by the Makuta Anima and Toa Idiotas.
