Last night, on the Slash2Podcast,
they mentioned this wonderful little guy who goes around lighting the lamps of Dalaran. Considering all the time that I have spent getting both Snazzie and Trixxyne the Achievement Higher Learning. I am amazed that I have never seen this amazing little chap. I did some research, and indeed, Windle Sparkleshine does go around lighting the lamps of Dalaran every evening at 9pm server. You can also buy your own little lamplighter from him! I must meet him!!
