The Three Sisters were a series of volcanoes in the Ice Spires South.[1]


The Three Sisters were semi-active volcanoes. They were connected to a complex of lava and steam vests leading deep into the depths of Toril. (These same steam vents connected to the Dour Fissure, a deep gorge farther to the north.[2]) So much heat was in the ground of the foothills of the Three Sisters that the small dale adjacent to the hills was on average 25° warmer than the surrounding valley. This increased temperature allowed for limited agriculture, which provided much of the food for the kingdom of Hartsvale.[1]


The Three Sisters were considered a part of the Firecap Mountains, which were themselves a part of the Ice Spires.[1]
