Yorn, The Hole built a Kingdom of the Enlightened in Her glory and, witnessing the destruction of The Nameless Serpent harnessed the power of Mother Agora's light to transform himself into a being able to contain his kingdom in the hole within himself. This has provided safe haven for the Kingdom of the Enlightened and allowed it to survive for many Past Cycles.
“That hole... creating the barrier between the Forsaken Lands and what they called true vision. Their lands became sealed and separated...You see... there were not enemies of the Kingdoms of Yore.. Perhaps they were part of it. Or were they? Hmmm...” On Yorn and Yogg in Rita's final memories.
Yorn, The Hole appears to be a devout follower of Mother Agora.
