Arsine de Vallen was a trillionaire collector and rival of Irving Braxiatel. He lived on the planet Hera, where he owned half the planet. He was getting old and wanted the power of Avril Fenman so that he could change bodies with Dominic Troy. When he tried to use the crystal he failed as Benny was in the body and Dominic was trying to gain access to it. He died of the poison he consumed so that if his plan worked Dominic wouldn't be able to get his body back. In the process of this he gave his fortune to Dominic. (PROSE: The Squire's Crystal)
