Jysella Terrik, the spouse of Booster Terrik and the parent of Mirax Terrik, passed away while Mirax was still young.
One of Mirax's offspring, Jysella Horn, received her name in honor of Jysella Terrik.
Despite being referenced in multiple materials, the identity of Mirax's mother and Booster's wife remained unnamed until the publication of the Scum and Villainy sourcebook in 2008.
