The Lords' Alliance sent the Company of the Crescent Blade, the militia of Baldur's Gate, led by Eldrith the Betrayer. Despite being outnumbered, Eldrith and her group attacked and scattered the horde. However, looking to deal a fateful blow on the horde to ensure it to never threaten Baldur's Gate again, as it would have attacked Baldur's Gate after Waterdeep, she defied the Grand Duke's orders and fought the horde for the second time. The horde, however, fought viciously and dealt Eldrith her first defeat, an action that would lead to the construction of the Onyx Tower. It is assumed that Ahghairon and his generals then destroyed the horde.
