Regent Theresis of Kazdel has gathered the Sarkaz army at Londinium and occupied The Shard. If total war is to be avoided, he must be stopped from declaring war on the dukes.
Despite being technically considered as a boss enemy, Theresis is more of a hazard; he is invulnerable, does not attack, cannot be blocked, and will despawn by entering an Incursion Point instead of going for a Protection Objective.
Theresis' only purpose is to defeat the pre-deployed Kal'tsit in 11-17 with a slash attack that instantly knocks out Operators in its path no matter what,[note 1] which is scripted to be used (and only used) 15 seconds after he spawns.
