Alexis is one of Lord Wilfried's guard knights. To improve his skill at gewinnen to a level where he would be competitive with his fellow archduke candidates of other duchies Wilfried often plays practice games against his retainers. In these matches Alexis most times comes out on top, with Wilfried only managing to win the occasional game against the much more experienced apprentice knight.
