Upon their defeat their bodies were dragged into the Limbo Plane , and their equipment with them . It is most likely that Isair carried a greater version of the Iyachtu Xvim ' s scimitar . History . Isair and Madae were born in the town of Kuldahar in Icewind Dale about a year after the troubles with the devil general Belhifet . Belhifet had launched a campaign to take over the Ten Towns and one of his evil acts had involved seeding many human and elven females with his own spawn . One of these , the elven woman Maiden Ilmadia Bariel , who was one of Belhifet ' s lieutenants , was rescued and resurrected by the Ilmater priestess , Mother Egenia , and brought to live with her in Kuldahar . After a time it was discovered that Ilmadia was pregnant . With Egenia and the Archdruid Iselore ' s help , she gave birth to twins . The children , however , had hideous disfigurements ; scaly red wings , thick twisted legs and tails . They were Half - fiends . Unable to take any more , the elven mother fled from the house and threw herself off a cliff , where her body was never recovered . The Archdruid didn ' t have the heart to destroy the children , despite their demonic heritage , and named them after his parents . The boy was Isair , the girl Madae . Despite his own trepidations he allowed Egenia to raise them in the town . She raised them for a time , shielding them from the hate of the other citizens of Kuldahar and raising them in the faith of Ilmater . When Egenia died , however , the townsmen grew anxious and confronted the twins . The twins delicate upbringing shattered , their devilish instincts took over , and they flew from the town . They escaped to Luskan where they lived on the streets for a time . After they had grown to maturity , they went to the Abyss al Plane to meet their father and join in the legions of hellspawn in the Blood War . They were horrified to find that they were no more accepted in this society than in the world of men , and went back to the Mortal Plane in disgust . They soon flew to the abandoned elven stronghold , the Severed Hand , where they began plans to raise a campaign that would sweep over Faerûn . They wanted to build a society that would accept all half - breeds and destroy those who had oppressed or opposed them . This campaign became known as the Legion of the Chimera . After sacking Bremen and Targos , Isair and Madae met their end against a band of adventurers that would have none of their tyrannical exploits . Deaths . Despite their great power and influence , Isair and Madae made a great mistake in choosing the Severed Hand as their headquarters . Formerly the Hand of the Seldarine , the Severed Hand was an elven stronghold that had fallen in the war between the Elves and the Orcs . Larrel , the elven archmage , had attempted to protect their home by laying a powerful elven protection shield , known as a mythal , upon the area . Although it ultimately failed , the mythal remained upon the stronghold even until the Half - fiends came to reside there . Isair and Madae cast many spells upon the Severed Hand in order to bolster their own fiendish powers as well as the defenses of the structure . Madae , a priestess of Iyachtu Xvim , invoked her deity during one of these great spells . The hateful power of Xvim corrupted the mythal , which reacted to this awful power by trying to bind itself to another plane in order to stabilize itself . The plane it chose was the Plane of Limbo , the Chaos Plane . Orrik the Gray , a resident wizard of one of the Severed Hand ' s towers , informed the Half - fiends of this disaster , but they accused him of lying , and ignored his warnings . When a group of fateful adventurers confronted the twins for their evil actions and battled , the mythal completely attached itself to the Chaos Plane . Isair and Madae , weakened as they were from battle and as connected as they were to the defenses on the Hand , were dragged into the Plane , their pained screams echoing throughout the collapsing stronghold . They were never heard of again . References . Sources . Icewind Dale II
