Dhian orbits close to the system’s red dwarf star and burns hot throughout its orbit. Were it not for the essential mining operations and position as a shipping and passenger terminus, there would be little reason to colonise it. While the mining operations were well supported in the beginning, the technology has allowed to degrade and fall into disrepair and the dangerous operations are really only possible because of the restrictive practices of the controlling government and few of the passengers or freighters notice the working conditions as most business is dealt with on the star port.
