Cayde went to a magical school where he was a mid-pack student, before he got suspended for conducting illegal magical experiments. He was then transferred to the Arcanamirium magic school, where he did the same thing but under the instructions of the dark lord Azmodius, and once his unholy experiments were discovered by the school, he was placed under arrest and scheduled for execution. He managed to escape confinement and stowed away on a cargo ship where he met a group of Abrogail Thrune’s servants known as Ninth Knot. The squad invited Cayde to join their group after he helped them defeat some water elementals onboard the ship.
Fought in the Ruby Phoenix Tournament, sent to the Negative Energy Plane by Hao Kahn, where he probably died shortly after.
