Arl of Denerim's Estate - Dungeon

Characters

Arl of Denerim

Howe Guard: After a very brief dialog he (and his colleagues) attack regardless of the dialog option chosen.
Arl Howe He will engage in dialog the moment you enter. No matter what dialog you choose it will always end in combat.

Prisoners

Rexel: The poor man has gone mad from prolonged torture. The Warden can free or kill him to complete the quest Missing in Action.
Soris: An elf locked up here for quite some time, he will be free after a short dialog with The Warden. If the Warden is a City Elf and took responsibility for killing Vaughan, then he will not be here.
Vaughan: The son of the Arl of Denerim. He can be freed, killed, or forced to remain. See his article for details. Not present if slain during City Elf Origin.
Irminric: A templar going crazy from Lyrium withdrawal; choosing to help him begins Lost Templar.
Oswyn: A dialogue with him begins Tortured Noble.

Note: To speak with these characters, right-click on their cell door (as if to unlock it). Right-clicking on the character triggers a brief comment, but does not initiate the dialogues noted above.

Bug! Clicking on Vaughan first before the cell door may make it impossible to free him, the door will begin giving the same brief comment as clicking on Vaughan directly (the door remains locked). Reloading before clicking on Vaughan first will be required.
