I don't know if I'd feel comfortable enough for Neytiri, sorry. If I see a Neytiri player, I will definitely send them your way if you don't mind.
If you'd like to do something from Dragon Age, I've got a couple characters I could play against any of those that you've listed. Rimilda Cousland (tainted_blood), Keishara Marahiel (wayofthreetrees), or Acaraena Surana... who has a journal but there's nothing in it aside from icons. She's just an OC elf mage [I used the warden last name since I couldn't think of one when I needed her for a line lol]. I'd really prefer to use them but if needed, I could NPC Morrigan and maybe Leliana. I'd be up for re-doing things or post-Blight, whichever! Rimilda and Keishara both come from post-Blight, post-Awakenings, but that's easily fixed.
