This lightly-wooded area has seen a number of clashes during the Conquest and is littered with the remnants of combat. The Old Thicket does offer a more direct route to Lethian's Crossing than the dense forests surrounding it, and is thus still used by traders unfazed by the occasional corpse lining their path.
Points of interest
Minor loot is spread over the area, with a single merchant in the center. Talking to him triggers a Bronze Brotherhood ambush.
