(Darkstone) n. A dark and forbidding castle located west and slightly north of Wehnimer's Landing, named after the nearby Darkstone Bay. Home to some of the immediate region's most feared beings, including stone sentinels, banshees, massive troll kings and Sheruvian harbingers. The sorcerer Estrion and the wizard Siarl attempted to use Darkstone as a base from which to launch a campaign to destroy Wehnimer's Landing. They called upon Sheru to assist them, but their magic experiments and unholy rituals backfired, creating the storm of mana that lingers above the Castle to this day. Sheru abandoned the pair, though the wicked harbingers who heralded his arrival were left behind. Estrion and Siarl then launched a failed attack on the Landing. Estrion was slain by Starsnuffer, while Siarl managed to escape. His whereabouts today are unknown.
