I think Eris lived in her ship she always hung around it and when TTK dropped and her ship went kaboom she moved downstairs in to shelter so does she rent a room or something. where does she live if it's in the tower she has nothing to pay with, nobody buys anything off her all she has to offer is raisins and black goop so if you think she's homeless leave a bump or tell me your theory on not sure what to think but this is my idea of how she lives now.
