I met Krilge while making Mooncloth in Ashenvale. He was stationed there to protect civilians from danger, until he disappeared... They've stopped looking for him and consider him a deserter, but I don't believe it. We would often meet at Fallen Sky Lake before it became overrun by those aggressive bog beasts. I'm not typically one to ask favors, but if you could go to Ashenvale and look for any sign of him, I'd appreciate it.
