I'd love to hear more about the lore here! Are they a god of displacer beasts?

Hes a sort of mythical hunter for the githyanki actually! He was blessed with the ability to not only teleport through space but also dimensions, which left him somewhat mad. He hunts down mindflayers and will often hunt and kill other displacer beasts who are under the control of the mindflayers, and take the young to train as hunters in his stead. while unstable he is generally seen as good willed and sometimes comes to the aid of githyanki who have helped fight mindflayers in the past
