Tarrnesh is a serious looking teenager on the cusp of adulthood. He keeps himself clean-shaven and his head shaved as well. He claims that it allows the wisdom of Sun Hawk to enter his mind more freely. He isn't as strong as one would expect, given the harsh environment and upbringing one would experience among the Praxian Bison Riders, but he is not weak, since Prax does not suffer weakness. Instead he is slim, and fit enough to keep up with the others.

However, his best talents lie in his memory, his oratorical skills, and his intelligence, to say nothing of his increasing connection with the spirits of the land, particularily Sun Hawk.

His family owns 120 Bison, and among them is his own personal riding Bison, Grumpfy.

His mother is Nama Len a follower of Daka Fal, the third wife of Colnar Three Steps a Waha elder.
His half brother is Kobal.

Tarnessh will:

-Choose negotiation over fighting if dealing with other humans or non-hostile nonhumans, because he's a much better talker then fighter.
-He will always be hostile to Chaos, although he won't immediately fight them if he feels that they're at a disadvantage. He will, however, always consider ways or plans to destroy them.
-He prefers to be active during the day and will be more hesitant to take risks at night, because he's much weaker when the sun isn't in the sky
-He'll obviously choose to defend other Wandering Rangers and members of his clan
-He prefers to keep the group together.
