I was looking up videos of Corrupted Ashbringer, when I came across this one: http://www.youtube.com/watch?v=EWox1...eature=related.
About 1:30 into the video, the filmer stumbles upon a fallen elf, wearing T2 mage set. Having been in Naxx40 in Vanilla myself, it was odd seeing this character in vanilla naxx, but not wotlk naxx. I decided to research him, and found out some very interesting information.
It is quite sad lore-wise what has happened to him, but you can read for yourselves: http://www.wowwiki.com/Tarsis_Kir-Moldir.
