Cover art for Autumn's Grief lyrics by Eternal Tears of Sorrow

This song is straight and simple - about a romance ending in a joined suicide, that expresses the endlessness of the love (much like in HIM's "Join Me").

My favorite lines are "This crimson stream will be the final step on the path of our mortal lives", which shows they will commit suicide by cutting their wrists (or any other main vein).
