Home of the Akakals

The home of the Akakals is a sheet of two dimensional space, the only one not destroyed by the Last Purge. It is home to the Akakals, a telepathic hive mind race who are infinitely benevolent. They accommodated every species they could, and after the Last Purge, they began creating colonies of genetically engineered races to rebuild. according to the Prophecy of the Katineth, once only the Orax/Lego Figures and the Katineth remain, the Son of the Un-named blackness shall rise up and destroy the universe. The Akakals and their "room mates" live in a largely subterranean existence, eating food pellets coated in a flavor giving liquid mined out of the earth, like all of their other resources.

After their genetically engineered colonies had become independent and began to rival the Akakals in power, they underwent a process leading to their departure from known reality.

First they time locked their plane, then began using all of their telepathic power to construct an exotic matter boundary separating them from anything else. They destroyed any portals leading in or out, and then with Brift's help began to cut their space out from reality, taking a segment of the lower planes, the Gates of Ascension, and the Time Vortex. At this point there was a 50% chance that the home of the Akakals would be utterly destroyed except for the 2nd dimensional keystone, and a 50% chance that everything but them would be utterly destroyed, as well as the 2nd dimensional keystone. This lead to reality splitting with one reality where everything else was destroyed and another where they were, effectively separating the two. Vaatu and Raava were killed in both. In the Akakal reality, there is only the 2nd dimension.
