Situated where the trail from Castle Krag joins the North Ride, the pool was a major defense during the Battle of Shadowdale that took place during the Time of Trouble. It was here that the Zhentilar (Zhentil Keep forces) were decimated by invisible deadfall trees which fell on them once they had moved past the initial defenses.
The area around the pool remains cleared, as the woods have yet to fully reclaim this area. The area around the pool is also littered with rocks and stones pulled from Castle Krag and used to build temporary battlements.
