I have three reps that i use almost constantly
Amrith Sa'al Cayin, or Amrith Sal Cayin, whom is my eldest...in more ways then one... started out as a story character for a story whom was a faerie folk, a being related to Elves (looked alot like them) mostly looks like an elf when i use him... tempted to put antlers on him...lol

Gilarin Amidranel, which you've no doubt seen a recent post of his pick by Danboyya2000 , he's taken many shapes over the years, first as an elf kid (if i remember correctly) in the same story as Amrith, then evolving into a cat boy like being which is what he is depicted as now, which is now since the pic his perminate form

The third one is:
Celethiel Gadbeyl: I first started coming up with him while playing Elderscrolls, using their Aylied language which i might add his name isn't of simply because though it is similar to their language i couldn't find anything that sounded right... really doesn't have a form yet....lol

Their names i came up with myself out of my own mind ^_^ I don't know are they OC's....
