Ahlrada Ahn was ostensibly a Tiste Edur however, unknown to the Edur, he was of Bluerose Tiste Andii descent, and one of their spies or "watchers" on them. Born the child of spies, he was thoroughly integrated into Edur culture but retained the legacy of his ancestry.
Ahlrada Ahn participated in the Edur invasion of Lether as a part of Trull Sengar's squad.
Ahlrada always regretted his role in Trull's shorning and thought himself a coward for following Rhulad as he had always admired Trull and believed him to be innocent.
He was later among the Edur expedition that tried to conquer the First Throne, which was being defended by Trull Sengar and Minala and her 'children' army along with a few T'lan Imass. Recognizing Trull, he acted on all his previous regrets and immediately killed those fighting alongside him and joined Trull in defending the children.
