Deep Imaskari are heirs to the lost empire of Imaskar. Few have survived when their slaves, having been abducted from other worlds and magical monsters (phaerimm) created by the war wizards of the Imaskari, were turned against them. Their empire crumbled leaving only ancient cities becoming ruins. Those few that survived fled deep down beneath the surface of Faerûn, purposely shutting themselves off from the events of the surfaceworld.
