Unsala was a galaxy known to the Anschlasom. From the perspective of the Milky Way Galaxy, Unsala lay beyond Vesra. In turn, Pesh was beyond Unsala along the route to the distant Som. 

History
Billions of years ago, Unsala was known to the Anschlasom. When a group of them passing through the Som stranded on the Mikhal Outpost 10,000 years ago, they carved their astronomical knowledge into stone and a cave. Unsala was depicted on an artefact, one in a series arranged in the Fibonacci sequence

In August 2381, Federation Fleet Commander Afsarah Eden, Counselor Hugh Cambridge and the Doctor travelled to the Mikhal Outpost to investigate Eden's origin, which was linked to the Anschlasom. Looking on the artefacts, Eden remembered the names of Anschlasom constellations and galaxies.
