Orion-Riit was a Kzintosh who resided on Wunderland around 2435 C.E. As a son of Vaemar and grandson of the great Chuut-Riit, he was a member of the Riit Clan and therefore considered royalty by the Wunderkzin. Orion used his family's considerable wealth to finance the refurnishing of the ship Hispanola and its conversion into the Valiant. The ship was used on a mission to Garth, in which Orion actively participated, to recover a purported treasure left by the pirate K'zaar. It was through Orion's daughter Marthar that he first became aware of the location of the fabled Treasure Plant.
