Quesseer was a Netherese settlement founded in -2368 DR by Arthindol the Terraseer, just to the north of the Sword Mountains. During its lifetime, the town became a trading center for the towns of Illusk and Waterdeep, as well as for the elves of the forests of Illefarn. It was eventually abandoned in -2095 DR due to the destruction of Illusk by an orcish horde from the North and the threat of destruction as well.
