Eternal Life: Fog City

Fog City, a steam port city shrouded in gray fog all year round. There is a pawnshop in the city called "Changshengdang" that does not accept dead objects. Instead, it accepts intangible things such as people's names, memories, voices, dreams, etc. Rules: Money should be money, things should be things, names should be names, life should be life; things should be redeemed, but names can be redeemed forever. People who have pawned their names for too long will become "empty people" - no self, wandering in the fog, and come back to "ask for pawns".
