Harpori A is a barren, lifeless rock with no atmosphere, and barely a seventh of the gravitational pull that Harpori has, though it is still rich in light elements and trace metals. It has only an eleven hour day, however, and orbits Harpori three times for every one of Harpori A’s days.

There are a few cities on the surface, though most of these are military installations and low-gravity training facilities. The others are small scale mining enterprises that have been set up to extract the veins of precious metals and gemstones that have been detected near the moon’s core.
