Umbra

Umbra is the second and smallest satellite orbiting the planet Solum.

Unlike its larger counterpart Ignis, Umbra has its own orbit and lies just outside the gravitational fields of any other celestial bodies. How exactly it stays within orbit of Solum remains a mystery.

Umbra is a relatively small moon and is roughly 3% of its primary's size. Most of the surface is believed to exist out of a dark igneous rock, but the lack and difficulty of astronomical research has caused its exact features to be largely unknown.

Due to its vast distance and small size, Umbra does not show lunar phases but rather suddenly disappears as it falls into the shadow of another celestial body.
