Chusi ... I'm stuck with short and "i" at the end for the boy ...
somethig like Walking-With-Spirits or Spiritwarrior as adult name
Or Walks-among-Us as the Timeless name ... Ataciara (Atacary)
Illiivat (Illjavat) - YoungOne-Who-Learns
Personally I like 1. Touched, 2. Walking-Among-Spirits and 3. YoungOne-Who-Learns for the meanings. Needs sound-names for 1. and 3. ...
Another adult name could be Hard'ToScare or Ghostwisperer (someone who can handle the "ghosts" of Nightmare Forest.
I don't think the Jenhna or Timeless would point out the fact that he has saved Ennits.
