You must have favored Meredith in the dialogue at the beginning of Act 3. You must have completed some quests before it will be acquirable. Head to The Hanged Man at night and a bartender there will tell you that some men are waiting for you.
Talk with Ser Mettin and Ser Agatha in the Hanged Man. Head towards Darktown and into the Hidden Sewer and kill off all the Blood Mages in the area. You don't have to read all the letters lying around to continue the mission. Once they're all killed off head back towards your Estate and read the letter from Ser Mettin.
Go through Sundermount Caverns into the Graveyard, head towards the quest marker and enter the Blood Mage Refuge. Ser Mettin and Ser Agatha will assist you in killing off the blood mages in this area. Mettin will then wish to kill the others assisting the mages there as well, which Agatha disagrees to. You have the option to side with Mettin or Agatha. If you refuse to take sides, Mettin will consider you Agatha's supporter. More templars will arrive, half of them standing by each of the leaders. Kill Mettin or Agatha and the templars who chose to follow them. In a short dialogue the surviving templar will thank you for help and promise their support. The quest will finish after that.
Optional: After the fight, unlock the complex chest next to the shrine for The Vague Blade.
- No matter whom you decide to help in the second fight, the templars promise to provide future assistance.
- 810 XP (for the fight)
- 330 XP (second fight - no matter whom you decide to help)
- Templar helmet - heavy issue may drop from Ser Mettin (low drop chance).
