A Knight Marshal is an officer within the Guild of Free Adventurers responsible for keeping order and enforcing laws and guild protocol. The marshal inspects weapons, oversees combat training and duels, and has the power to arrest members who misbehave.

Sir William Misslefire is the Senior Knight Marshal and can usually be found at the Main Hall in Evenhold, though he regularly visits all guild sites. Deputy marshals assist Misslefire at the hall or help oversee activity at other guild-managed locations such as the Beginners Cave or the Beginners Forest.
