Talk to Lieutenant Rinah to learn about the heretic's death and his brothers' plans to bury him in the cemetery.
Help me get rid of the three stubborn brothers!
I see you're ready for your first assignment! Okay then, let's start with something simple. Yesterday a heretic in our dungeon died during an embarrassing interrogation. We hid the body near the city wall, but apparently we weren't careful enough. Someone saw us and told the dead man's brothers. Now the three of them are probably going to try and dig up the body in order to bury it in the cemetery. We can't allow this, we will not tolerate heretics in the cemetery! Let's go to the spot together and get rid of those three good-for-nothing men!
Head out of the dungeon the same way you got to Rinah. Although the location indicator on the map looks like it might be inside the city walls, it isn’t. Fortunately the Inquisition tend to be lazy about corpse disposal, and there’s a handy gap in the walls around the gardens. Head southwest from the Temple building down to the lower level of the gardens, then make for the southeast wall. Halfway down its length is a gap beyond which three brothers are standing around a fresh grave.
The quest will update when you pass through the gap, and one of the Vengeful Brothers will have an exclamation mark (!) over his head. Talk to him, then kill the three when they become hostile, making sure to keep an eye on Lieutenant Rinah’s health.
Brothers! There! There's two of them! REVENGE FOR BROTHER JOHANNES!
When they’re dead, talk to Lieutenant Rinah for your reward.
Very good! We showed those rebels, didn't we? If you're looking to complete any more assignments, you know where to find me. Excuse me for taking the shortcut. After all, time is gold!
If you want to talk to her again for the next quest in the chain, Inquisitor Monwarion, you will need to go back down to where you originally found her.
