Brencis's Flags are five banners hung in the gatehouses of Svartrau City. Cut all of them down to earn Capture the Flag, but expect guards and a rise in Infamy.
All five sit at Svartrau's gates. Guides name the gates differently, so check the city map and work round the walls rather than trusting one gate name.
Climb onto the wall, get into the gatehouse, deal with the guards and cut or destroy the banner. Night lets you use Shadowstep to get up the walls faster.
The main payoff is the Capture the Flag trophy. Watch your Infamy, since every banner you take down pushes it up.
