In The Gutter

You see a downtrodden knight sitting out the festivities next to a pair of sabatons that visibly appear to be too small for him. He catches your gaze and grunts, "That pyromancer's display by the Bright Wizard College blew me off my feet. Landed by the sewer entrance I did, in a daze but still alive. Next thing I know some little hands reach out the grate and steal my sabatons! I pressed that pyromancer for recompense and all he gave me were this pair, too small for my feet! I haven't a coin left to buy a proper pair, only this lucky gold horseshoe. I know somewhere down in those sewers my sabatons are waiting for me. Can you help, |c?"

Venture into the Altdorf Sewers and kill its nasty denizens until you find the Unlucky Knight's sabatons. Return to the Unlucky Knight when done.
