Well that's some sort of explanation:
Once upon a time in a land far away which was called Rivelon there lived a Troll King who in his spare time between looting people, started to practice bow shooting. As he was a king he didn't bother to pick up the arrows he had already fired. Unfortunately the troll king never became an expert bowman because he was slain by some adventurer who was passing by the King's cave..
Doesn't make much sense, but then again does it have to make sense? <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
