The Arena Guard's Problem

Halt! Identify yourself! If you value your life, you'll tell me what you're doing here. Wait, you're no traveler... Sorry for all that yelling earlier. I know it's no excuse, but I'm sick of travelers blithely skipping by. Ignoring me, even though it means their very lives. I am Zen, the patrol leader for Battle Leader Kun. We've been working for months. I'm exhausted. Could you help me kill the Skinwalkers in the surrounding wilderness?
