Looking for Lore writer for my concept

Amongst the styles of martial arts in Ionia, all have their secrets; techniques so destructive, they were hidden away from the eyes of the world. Even the mystical school of Wuju was no exception. Long before it's current state the Wuju were a barbaric society were an inhuman being known as Zimn ruled them. The Wuju did not know What Zimn or the 4 others that visit from time to time were but they knew is these 5 were very strong. In exchange for loyalty Zimn would give them knowledge but this was to be his downfall. For the Wuju were planning to take all his knowledge and power.

what needs to be said Zimn is a Darkin or half Darkin & half Human Hybrid Zimn was captured by 's ancestor. Where he was sealed away and an item which the Wuju stole from him and they used this item as the key to the seal and is part of a inducting of Wuju masters.
