Isthmus (Planet)

Isthmus is a water-world which lay in the Tangiers System, at the very edge of the solar system's habitable zone. A world rich in deuterium, it was settled by Tangerians in the early phase of their expansion.

The population of Isthmus never amounted to more than a few hundred thousand, the world being nearly completely devoid of natural land, and its weather being a near constant rainfall and storm.

The planetary capital is Port Isthmus, a city situated on the only major island of Isthmus.
