Prefacing by stating I started out as a Mooncat with a Mooncat-based name, and became known by said name and didn't want to change it as a result. XP

Miyha is essentially a Miqo'te-fied version of "Mia" (both pronounced mee-yah btw), a name I've used in the past. Manaya just happened to be the last name of a favorite boss in a previous MMO I played (Shandra Manaya from TERA), and its spelling patterns seemed like it could work as one of the "lesser Keeper tribes" referenced in the lore. How I explain this name being attributed to an Au Ra: she was adopted. |D

Her birth name I decided is Kahlan Kagon, Kagon being the moon-worshipping tribe of Xaela residing in the Nhaama Desert, and Kahlan being a favorite character in one of my favorite books, also a possible spelling variant of Khulan, a wife of Genghis Kahn.
