Screaming Whisper, Ballad of Rebirth.

Do scars ever heal? After thousands of lifetimes, someone can lose track of their sense of self. His scars would never truly heal, because they marred his soul. He could not hold all the memories; lovers, friends, and foes simply forgotten. If the deceased could live on in memories then he truly was the reaper of millions. He held witness the rise and fall of countless dynasties, and saw countless mistakes repeated. He had butchered thousands, but he could not even answer why. Perhaps it was to feel something other than emptiness. The minstrels of the Ethruhiel have sung his ballad for thousands of years as it slowly lost meaning. Yes, it is possible for gods to die, however unorthodox it may seem. To be forgotten is the ultimate death. That is what he sought.
