High General Brigitte Abbendis was possibly the most fanatical of the leaders of the Scarlet Crusade. With little thought or hesitation, sacrificed her troops in her unending conquest to destroy the undead of Azeroth. She followed in the footsteps of her father, High General Abbendis who helped to found the Scarlet Crusade.
She kept a detailed account of her campaigns in a diary.
Brigitte was given the task of completing her father's mission before he met his death at the hands of the undead he sought to eradicate.She became a member of the Knights of the Silver Hand, and was witness to Alexendros Mograine's plans to create Ashbringer. She aided in this by helping to cleanse the crystal in the sword. This meeting in the Southshore inn was also attended by Tirion Fordring and Isillen. Arcanist Doan, who had feelings for her, was also at this meeting.
When her father died, Brigitte was given the title of High General to replace him.
World of Warcraft
As High General, Brigitte took great lengths to protect the bastions of the Scarlet Crusade's powers. With the Eastern Plauguelands posing constant threat, she spent a great deal of time at Tyr's Hand. She was killed there by adventurers, but the Scarlet Crusade resurrected her.
Wrath of the Lich King
From Tyr's Hand, she did not have far to travel to jump to the defense of New Avalon when it was attacked by Death knights in the service of the Lich King. She also found herself, however, protecting the Scarlet Crusade from the panic of the Citizen's of Havenshire. The Death Knights watched this as they prepared for their full assault.
As New Avalon fell, a Death Knight took the guise of a Scarlet Courior and deliverd a message that had been intercepted to the High General. Brigitte was furious at the "Courier" for being late, although she knew the Death Knight forces were too powerful even if reinforcements were to arrive. She wrote a reply, though unbeknownst to her it would never reach the armies of Hearthglen and Tirisfal Glades that marched to her aid, announcing that the Scarlet Crusade was shifting its focus to Northrend and dubbing itself the Scarlet Onslaught.Before long, she had established New Hearthglen and took full command there. Unfortunately, neither the Horde nor the Alliance took well to her presence there. Commander Eligor Lightbringer of the Valiance Keep sent the heroes of the alliance to kill her. High Executer Worth of the Hand of Vengeance sent the Heroes of the Horde to similarly fetch her head. With both groups of mighty heroes set upon taking her life and removing all possibility of resurrection, her death became an inevitability.
When Abbendis was killed, High Abbot Landgren seized control of the Scarlet Onslaught.
