Zassaliss was a large male adder and the son of Berussca. He lived in Brockhall, where he was bound at the tail to his siblings Harssacss and Sesstra by the mace and chain of King Sarengo. Being bigger and stronger than the other two, he became the leader of the trio in their hunts as he wore a golden crown sporting two black jetstones; this was a crown previously worn by Sarengo.
