The hero will encounter Jesan Rilian for the first time when arriving at the Kvatch Oblivion Gate during the search for Martin. Jesan will, alongside two other Kvatch Guards, Merandil and recently promoted Captain Savlian Matius, hide behind the barricade near the Gate in a desperate attempt to keep the Daedra away; every time a new set of enemies spawn from the Gate, all three soldiers will run head-first into battle, then return to the barricade when the area is clear.
Attempting to speak with Jesan will only have him say, "Just follow Savlian's orders, and everything will be fine." If talking to Savlian and offering help, Jesan's greeting will change slightly: "Talk to Captain Matius if you need something. I'm just following his orders."
