The buildings were multistory, trapezoidal, made out of a gray material, and arranged in a half circle around a raised plaza in the center where the causeway ended. They had rib-like supports curving up from their bases that might be decorative, or maybe for power-generating, I had no idea. To the east around the front of the surface dock was a sea of green plants, fronds waving in the breeze. Increasing magnification as much as I could, I saw a structure under the greenery, probably growing racks supporting the growth medium off the ground, full of water and whatever else plants needed.
