Ulduar

Here's [Summergale's] first collaboration with Cranius, a highly talented musician and machinima producer, and the incredibly awesome machinima artist Legs. Without their help and huge contributions, this video would likely have never seen the light of day. (...)

"Ulduar" has a bit of a "Romeo and Juliet" theme, where the PvEer (sung by Summergale) is dating the PvPer (sung by Cranius). He's a punk and a bit of a rebel. She's a highly-skilled and geared raider. She wants to bring him along to her playground of choice, the newest most challenging raid instance. He wants nothing to do with it and wants to show her the dark side of PvP.
