THE CRIMSON OARS
The Crimson Oars is a quest received from Sergeant Kylon at the Denerim Market District after completing Pearls Before Swine but only if you completed that quest by not killing Mercenaries at The Pearl (otherwise he will no longer talk to you).
Sergeant Kylon has asked the Warden to deal with the mercenaries at the Gnawed Noble Tavern (Denerim District Place Map, L GT). This time he says you can use lethal force; the innkeeper doesn't mind some blood (or 'sport' as she says), so force may be used.
Walkthrough
To complete this quest, go to the Gnawed Noble Tavern and confront the Crimson Oars Leader (Denerim Other Locations Map, Gnawed Tavern, L7).
At this point you can either:
Let the Crimson Oars stay (this will not net any gold).
Kill the Crimson Oars (when the fight starts the door shuts behind you and cannot be opened until the fight is over).
Persuade / Intimidate them to leave peacefully.
Return to Sergeant Kylon for a reward.
Rewards
If the Crimson Oars left or were killed:
3 gold
100 XP
