The Great Tesmanian Cloud is the second companion galaxy of the Caladarian Galaxy, alongside the Angelina Spiral. Located about 40,000 light years north of the Caladarian Galactic Disk, the Great Tesmanian Cloud is the smaller of the two companion galaxies. It comprises of about sixteen billion stars spread across a distance of 20,000 light-years. From the thirteenth century AH, extra-galactic civilizations, such as the Marasahrite Empire and the Commonwealth of the Dejaniks, intruded into the Great Tesmanian Cloud by means of a wormhole, conquering most of that galaxy. In a series of wars and interventions in these states, the Laurasian Empire eventually brought this satellite galaxy under its rule in the eighteenth century AH.
