Second Great and Bountiful Human Empire

The Second Great and Bountiful Human Empire was a political entity with influence in three galaxies. By the 42nd century, it had spread from an overcrowded Earth throughout that galaxy of Mutter's Spiral and two others. These three galaxies were collectively referred to as the Tri-Galactic. The currency of the Empire was the credit. (DW: Planet of the Ood)

The Empire as a whole apparently had detailed knowledge of over 67,000 sentient species and sub-species, and had familiarity with at least 42,000 languages, 47,000 types of weapon, 56,000 vehicles and 81,032 hand to hand physical combat methods.
