Death Bridge

In Troll Bridge, this is the titular "troll bridge" guarded by Mica, and looks just as you'd expect it to: old, crumbling, and made of stone, with the only path to it being little-used as of Troll Bridge. It seems this bridge had been passed on to Mica, and has been in his family for many years, and he loved it and hoped to pass it on to his son. However, he also had a wife who didn't want her son to grow up just to be killed by some barbarian hero. As there is also mention of a troll by the same name in the City Watch, it is possible they did move to the city, in which case the bridge would now be abandoned.
