Monarch is a single yellow star in the Cygnus region. It has two major planets and 450 minor bodies.

The star is surrounded by a low-density dust cloud, which gives the sky a yellowish tinge at night and slightly dims the star's light.

In the Quiet Era, Monarch falls under the jurisdiction of the Caydlaw.
