Manas Nui

The spawn of Ashima, born disfigured and gruesome, isolated by Hafthure the Builder in their own pocket universe.

Conception
Ashima, though wed to Hafthure, engaged in licentious behavior with other beings including Krulem. From these unions she became pregnant with a monstrous brood, and Hafthure was so repulsed by them that he erected the Demon Universe betwixt Thogros and the Abyss. However, Hafthure was so unnerved by the Abyss and wary of the Manas Nui that he also constructed a so-called gateway universe to create a barrier between his world and these.

Generations
The original Manas Nui were able to manipulate compounding reality fractures on a level far surpassing the sorcerers of Thogros. Each subsequent generation lost that ability slowly until the species devolved into the multitudes of mindless, ravenous monstrosities. Many of the original Manas Nui persist, and rule over swaths of the demon universe.

On occasions where a Thogros-based entity opened a portal to their world bypassing Formin, lesser demons were able to cross first. The Manas Nui, being far more powerful and sometimes physically larger, were often delayed in crossing until the growing portal reached an advanced state. Once the Manas Nui crossed, there was little hope in stopping them. However, Darren's truce ensured that no Manas Nui came to Earth.

No Manas Nui ever crossed on Earth during the two invasions, due to the nature of the Colfka-dielmonshire gates opened by the Demon King, who was in fact a former denizen of the Abyss and not a true Manas Nui himself. However, on the Thrakr home world, a portal to the demon world was opened sufficiently long for Manas Nui to cross, and they quickly slaughtered the resident magicians. When Bulk took Tarzahk's staff and undid the timeline, this event was erased.

Manas Nui later crossed during the Thrakr End Times on the other continent and survived the nuclear bombardment. They and their legions crossed the sea and arrived as the Ark was taking off. The Manas Nui set about butchering the magician resistance while the lesser demons engaged the Borglundo. However, before the Manas Nui could take down the Ark, they encountered the Puppetcorpse and engaged that entity, later being wiped out by the Fahamara.

Trivia
-Each of the Manas Nui were more powerful than any Thogros native magician by an order of magnitude. Even the Prime Magician, possibly the most powerful mortal magic user in history could not match them.

-The name Manas Nui was derived from a primitive Polynesian culture that was all but wiped out by a demon incursion in ancient times. Funnily, no actual Manas Nui were involved in the raid, but the moniker was later adapted by Darren's society to refer to the fringe, powerful demon lords displaced by the Demon King.
