The Kierrn are a work in progress, a race incomplete. Much is left that needs to be written and explored, ideas that are only half-formed in my head. A novel and a race/guide book are in the works, though nothing has been published to date. Because of that I would ask that you not write about, RP (make a character of), or otherwise use the Kierrn at this time. Once I have established myself as their creator, and have gotten them published, use will be granted on a case-by-case basis. Thank you for your understanding and cooperation!
