Runi

The Runi are a type of evil tree spirits that work for the Devil. They are ghostly, wispy, and shredded in appearance, with a white and black "skin." These can be found on the island Grak. They were first created when some of the Henier treefolk on the island tried to take away all sin from their spirits and become immortal and all powerful. Led by Leafarm, they performed the satanic act, only for their sins to come out of them and materialized into what later became known as the Runi. But, in doing this evil act, they died whilst their previous evil came out of them; but, since they committed evil by materializing sins into a deadly, force of Hell, these treeads were saved, nor given power. Luckily, not that many treepeople did this act, for the tribe's leader foresaw what would happen so he warned the people about following Leafarm.

Though not native to the Demonworld, these could be described as Hellians due to being a force of Lucifer. [1]
