Endurance-of-Will

Endurance-of-Will, referred to simply as Endurance, was a Promethean Warrior-Servant.

Biography
Sometime before the human-Forerunner war, when the Ur-Didact decided to marry outside his rate, the Librarian gave him a choice to return to it, had he done so he would have married Endurance. However he chose the Librarian instead, a decision that caused Endurance to resent the Librarian for thousands of years. During the human-Forerunner war Endurance served as adjutant to Bitterness-of-the-Vanquished. She was considered one of the top strategists, often clashing with the Ur-Didact regarding battle strategy. Later near the end of the Forerunner-Flood war he requested her presence on Requiem, where she reluctantly supported the composing of his fellow Prometheans and the humans. The Librarian had followed him to Requiem and planned to imprison him in his Cryptum. Initially Endurance was willing to follow the Ur-Didact because he was her commander. The Librarian could tell Endurance did not fully support the Ur-Didact and convinced Endurance to help her by asking if she thought he was still the same person. After the Librarian knocked out the Ur-Didact, Endurance volunteered to stay behind and protect him. She allowed the Librarian to leave an imprint in the ancillas in order to leave a message for future visitors.

Description
Endurance was small for a Promethean, but possessed a catlike grace. She had simple battle armor, no decorations, or spikes. The Librarian remembered her as honorable and sensitive.
