Monstrous mayhem

In the nine realms of Sednir every 100 years 1000 soul are brought from other worlds to replace the souls that have been lost.

Normally when this happens all soul loss all of their memories and this time is no different except when one of the souls gets stuck in the lowest realm the void.

This has caused the fracturing of their soul but to hide that they messed up ####### forced the soul back together and put it through the reincarnation cycle which has caused some unforeseen changes to this soul in the form of their consciousness becoming brain dead but giving their subconscious and natural instincts their own consciousness
