'Lost' seems to be the inverse of 'Air': It explores dispossession and identity by forcing a bunch of people into one invented landscape instead of using many invented landscapes to keep people apart.

'Air' is what the world looks like: An inconvenient mashup of human politics and divine geography. We leave bits and pieces of ourselves and our history in every place we encounter.
