Fides and Charitas
Two significant natural satellites orbit Spes. Both satellites contain insufficient atmospheres for colonization, and the Borealins have never warmed to the prospect of domed settlements because of the close proximity of a Class 1 planet. In the last year, however, the Borealins on Spes surprised everyone by announcing plans to construct a large enclosed city on Fides. The city, named Refuge, will serve as a rallying point for the Spes populace should the terraforming of Spes fail. The project should take more than a decade to complete.
Fides appears to be the result of an ancient collision with Spes; its geological composition is a precise match for that of its planet. Charitas, the smaller moon by far, is simply an exceptional asteroid.
