Oubliette is a place to remember.

The zoku colony is near the prow of the city, in the Dust District, just above where the Atlas Quiet prepare Martian sand to bear the weight of the city. It is easy to see where the colony’s boundary lies: beneath the red dust clouds the wide avenues with their belle époque fronts and cherry trees give way to fairy-tale castles of diamond, like mathematics given physical form.
