Introduction
Have you not heard of Eldrith the Betrayer, the Traress of Swords, Eldrith of the Westering Sun? That she has been forgotten is an... irony of a sort.
The General of the Westering Sun
Eldrith was one of the greatest generals of the Sword Coast, commander of the Company of the Westering Sun, sworn sword and defender of Baldur's Gate™. She served with honor and distinction in the first and last seasons of the Sundering War. Her victories included the Crescent Port siege and the campaign against the Black Horde.
In all these battles, she was victorious. However, pride eventually burrowed into her heart, poisoning her spirit. Eldrith had fought too many battles and achieved too many victories, leading her to view the city of Baldur's Gate™ as her own.
The Great Betrayal
On the day of the Great Betrayal, Eldrith's company took the field against the Black Horde. They scattered the enemy forces, despite being outnumbered five to one. Although almost half their forces survived, most fled the field.
Eldrith was determined to pursue the retreating enemy. The Dukes of Baldur's Gate™ refused this request. They argued that too many good soldiers had been lost and that the people wanted no more blood and death.
Eldrith believed it was better to deal a deathblow to the Horde. She defied the Dukes and led her soldiers to their deaths. Far from Baldur's Gate™, she cornered the Horde in a narrow defile.
The Trap
Once their retreat was denied, the Horde proved more vicious than anticipated. Eldrith, fearful of losing the field, sent a messenger back to Baldur's Gate™ for reinforcements.
The reinforcements never came, and the Horde overran Eldrith's weakened troops. Eldrith survived, but many of the Company of the Westering Sun did not.
Exile and Execution
Eldrith became a creature consumed by fury. Wounded, she returned to Baldur's Gate™ to demand an audience with the Dukes. Instead, she was met at the gates and told that the walls would be forever closed to her and the Westering Sun.
She gathered the remaining Bladed Crescent and ordered her broken company to attack the city walls. She swore she would take the city from the Dukes and put them to the sword, calling it justice.
Eldrith's attack was like a charge of a maddened animal; it was suicide. The Westering Sun were slain almost to the man and driven from the city. They were hounded by the remaining troops of Baldur's Gate™ all the way to the Marsh of Chelimber.
As the last of her soldiers floundered and died within the marsh, the pursuing soldiers closed upon her. She was no longer recognizable, with blood caked on her armor. Dying but fueled by vengeance, she still struggled onwards.
Fearing her skills with the sword, the soldiers did not approach within arm's reach. Instead, they felled her from a distance with crossbow bolts. It was a cowardly execution, one without honor.
As Eldrith fell, she cursed Baldur's Gate™ and all within it. With her death, the Dark Alliance was born.
