When a blade dies, he is tranformed into a memory, and gets stuck in people's brains, and gradually decay into becoming, a "forgotten memory". How long it will take to completely become forgotten, depends on the intricate relationship between the remembering and the remembered. I saw my brother drown to death. And there was not a damn thing I could do about it. Now I have a memory of him. I remember his face. I remember his smile. I remember what he said while he was here. All the fucked up things he said... I remember. But I won't remember him forever. I will gradually forget about him, and one day, I would have forgotten about him. But he's not gone. He's still with me. He's right inside my brain, sleeping. Amongst many other forgotten memories.
