He collected the information about the Skandians and reported to Haz'kam on their behavior to be un-strategic and single-minded. However, during the Battle of Skandia, the Skandians acted the opposite of his report, due to the help of the Ranger Halt.

After being mortally wounded by Will's archers, he reported his discovery to Haz'kam before dying.
