The Moat is the primary barrier between Northern and Central Tanglestone. It has its origin in a waterfall in the western mountain face, and flows out under the Wall on the eastern face. Three bridges once spanned the Moat, but at present only one survives: the easternmost was destroyed in a flood many years ago, and the westernmost destroyed during an invasion of the central city. The central bridge remains, though its southern ending is guarded by an infestation of trolls.
According to the Scholarium, the Shark zodiac golem patrols the Moat.
