Eldrith Eldrith the Betrayer , commonly known as the Betrayer , was a powerful warrior who served as general of the Company of the Crescent Blade in the city of Baldur ' s Gate . So masterful were her tactics , so well trained were her soldiers and such was her individual combat prowess that she never lost a battle . Her undefeated status fed her pride and she came to view Baldur ' s Gate as under her rulership , though she never actually staged a coup against the Grand Dukes . History . She led her forces to victory in the first and last seasons of the Sundering War , the Crescent Port siege and finally , the campaign against the Black Horde . However , at the end of that last campaign , despite being outnumbered five - to - one , she scattered the orc s of the horde . However half of the orcs number survived and fled . Eldrith was desperate to pursue them , to make sure the orcs would never return , but the Grand Dukes refused , citing the fact that too many of the best soldiers of the city had fallen already . Those that were left were weary and the people of the city wanted no more of death , earnestly believing the orcs would not return . Eldrith was furious and led her fanatically loyal troops , weary though they were , after the remnant of the horde . She cornered the orcs in a narrow defile , but with their avenue of retreat cut off , the orcs fought with greater ferocity , easily overwhelming Eldrith ' s outnumbered and tired warriors . Eldrith desperately sent a messenger for reinforcements but the messenger returned with word of the Dukes refusal to help . Eldrith ' s army was slaughtered but she and a few severely wounded survivors made it back to the city alive . At the gates , she was informed that due to her disobedience that she and her company had been banished . Again , furious at being barred from " her " city , she led the last ragtag remnants of her army in a siege of Baldur ' s Gate . The company was slain almost to a man and Eldrith reluctantly sounded the retreat . Baldur ' s Gate pursued though , all the way to the Marsh of Chelimber where the last of her followers finally foundered and was put to the sword . Eldrith was still alive , though it was a miracle that she was . Fueled by anger and hatred she kept to her feet , her face completely unrecognizable from wounds that should have killed her several times over . Her pursuers still feared her ability in melee combat and instead gave her a cowardly execution with a volley of crossbow bolts . Eldrith was finally brought down but her rage was insatiable and after the troops left , it was that rage which brought her back to life . Such was the power of her anger that not only did it grant her mysterious magical powers , it also brought into existance an Onyx Tower from which Eldrith plotted her revenge . She forged a Dark Alliance with various monsters , drow , lizardmen and the Baldur ' s Gate Thieves Guild , also discovering an artifact with great power over the undead that she used to raise many such creatures in the crypts and sewers beneath the city . Karne , leader of the Thieves Guild , robbed a trio of adventurers who then determinedly tried to track down their stolen equipment and were sucked into defeating Eldrith ' s machinations by the Harpers . These adventurers quickly grew in power and tracked Eldrith back to the Onyx Tower where they eventually confronted her . When Eldrith was defeated , she finally expressed remorse for her evil actions , succumbing to death at last . Her life and the powers that were tied to her rage and anger faded along with it , including the Onyx Tower which collapsed moments later .
