Crea is supposed to be that otherworldly force in the first place. Also remember these short stories can be lengthy and an empty Columbia can still have many characters, remember some of these stories will be split into parts so they can create a good story. Though anything to do with Columbia and Rapture will be short stories as they have already been done and there isn't much to tell anymore except maybe an aftermath, another character's perspective or an alternate reality.
