Cahir is an Orlesian soldier. He is Duke Prosper's personal guard.
In Mark of the Assassin, when Hawke is in the dungeons, he has the choice to escape by going through a cave or by going up some stairs.
If he chooses to go up the stairs into the vaults, Duke Prosper will stop him and tell Cahir to eliminate him. Cahir will then unleash the beasts.
If Hawke chooses to go through the crack in the wall into a cave, Cahir and some crazed mages will intercept Hawke, separating Tallis from the rest of the group. A fight will then ensue.
At the end of the fight, Hawke and the others kill Cahir.
