Aurora

Far in the outer reaches, with apoapsis beyond that of Coldstream, orbits the small, icy skylith Aurora.  Ideally situated for Silver dragonborn and maybe Silver dragons, the skylith is currently uninhabited after a Red dragon destroyed and ransacked the settlements there.  The surviving Silver dragonborn became refugees on Coldstream; the disposition of any Silver dragon which may or many not have lived there is unknown.

Gravity:

fairly strong, with slight but noticable diurnal variation

Rocky and icy, but with sheltered valleys for growing food, now gone wild
