"And when you die, you'll join my army too."
An evil necromancer defeated by the heroes of Memory Haven. Over the course of several years, he became a consistent threat to the new town. In a final battle, he stretched his summoning of the undead too far and Augustin was able to take control of several of the necromancers personal guard. William was greatly wounded and retreated.
A large number of years passed before Soliune was seen again. He showed up at the gates of Memory Haven to prove the worth of his undead army. He claimed his undead minions would destroy Toben. When the assault came, his creations were subverted and turned on him. He was ripped to pieces and devoured by his own servants.
