Righley Killiarn was said to be the most fearsome duelist in the Unapproachable East, having successfully survived over 250 challenges to his honor. This amazing streak came to an end, however, when he unwisely challenged a Thayan wizard who took the precaution to magically protect herself from spells known to every apprentice.

It seems duels are much harder when you actually have to fire the crossbow!
