The ocean, just outside, seeped into everything. An olfactory reminder to everyone passing through the Ellis Island of the space age that Earth was absolutely unique to the human race. The birthplace of everything. The salt water flowing in everyone’s veins first pulled from the same oceans right outside the building. The seas had been around longer than humans, had helped create them, and then when they were all dead, it’d take their water back without a thought.
