Though this world is hot enough to boil water during the day, deep underground liquid water can be found; it occasionally even rises to the surface at night. Voran colonies on the planet take advantage of this water using extremely deep wells.
The colonies on Arid must be under domes to protect from the heat and radiation, as well as to keep the water drilled from the wells from evaporating away and hold in air pressure. Life on Arid is hard, but survivable. Some of the more recently constructed domes are protected against the solar flare activity from the star; older ones are not. In practical terms, this has a subtle but crucial effect on Voran society. With Queens being unnecessary to survival, the Libertine culture tends to thrive in these protected domes.
