First, Winterborn - The Cruxshadows

And second, my personal favourite, Citadel - The Cruxshadows

I apologize for the sound quality in the second song, it was the only copy i could find on youtube. (correction, the only NON-remix copy i could find on youtube.) {second correction, TECHNICALLY this is the Isis remix, but it is the closest sounding to the original that i could find of the available ones on youtube.}
