Daimore, having been banished to the realm of the underworld sort to create and develop his land. Creating levels and areas of where mortals came to be with the Age that brought the races to the world. Where would they end up, would they make deals, was all this in revenge for what happened all those millennia ago.
These creations, not inherently evil but born through raw emotion, they would utilise the mortal souls and believed to gain power from many different sources as a way to break out of the prison that he had grow to adapt and build.
They were considered not friendly to Material Plane and were seen to have harmed or corrupted the area outside. They were forced to utilise the mortal souls in order to adapt and change, they existed within the Underworld within the Plane that circled the Abyss within, the darkest known depths of the plane where no light or darkness existed.
Due to the Raw emotion that was made to create them, they were known to be prone to extreme violence, cruelty and malice - they delight in war, the suffering of others brings them equal joy and they desire nothing short of the destruction of all things, valuing nothing save brutal strength, which is the only means to truly control them. However, there were some events where this didn’t quite happen and cracks showed throughout the surface.
