Lore

There is no self to kill; There is no end to life. The choices were made by someone else; The one who was who we were. We return, estranged, to act on them. We must stay unseen, like the ghosts we are: Take flight from the sun of living folk. Take the Ghost you were given— End the cycle that gave you birth; End those who killed you first.
