When Moss was born, he was actually a pretty normal foal, but after some unknown situation, he lost the ability to speak and gained unnerving intervals, telekinesis, and prophetic abilities. His bouts of madness being the only times he can speak. He's normally shy, quiet, kind, and helpful, but becomes this other version randomly, and during those intervals, is usually unaware of his surroundings; He twitches and cackles if he's not simply swaying behind his chosen companion, jabbering about nonsense that vaguely sounds like cryptic prophetic warnings of what's to come.

   Because of his strange 'prophetic insanity', many are put-off by him, which has made him self-conscious and very lonely. Moss just wants to have friends, basically, but his 'problem' makes it difficult.
