Taexalus

Taexalus is a small icy moon of the planet Calgacus and home to an Imperial research base.

Due to the moon's climate, it has never gained enough attraction as a colony. It has, however, been home to a small research base of the Adeptus Mechanicum called Improxus. This base has been a home for researching the system's various ruins and technologies left over from the days before colonisation.

At the outbreak of the Invasion of Mercatorius, the moon was attacked by both dissatisfied workers aligned to the Genestealer Cults and also the forces of Chaos, who sought to divide the Imperium's two planets in the Mercatorius System.
