I can remember a time when Lightfingers was a big Thief. He would challenge young knights and when he won (and of course he did) he would discuss the fight and tell them how to improve their fighting. He was one of the most helpful in all of Avalon for the young.
So you may be a mean old member of the dark now, Lightfingers, but you cant erase that memory in some.
Written by my hand on the 20th of Eleuthral, in the year 1304.
