Iruladoon was a quasi-extraplanar forest that was located on the eastern bank of Lac Dinneshere in Icewind Dale. It was created by Mielikki specifically for her apparent Chosen, Drizzt Do'Urden, in order to house and instruct his friends, the Companions of the Hall, prior to their reincarnations. In 1466 DR, Drizzt Do'Urden and his companions at the time (Dahlia Sin'felle, Artemis Entreri, Ambergris, Afafrenfere, and Effron) presumably spent a night here that turned out to last eighteen years in the outside world.. The demiplane seemed to disappear after they woke up in 1484 DR.
