Trans-Galactic Credits

Trans-Galactic Credits or "TGCs" are the official currency of the Castor Alliance.

Initially every world in the Castor Alliance had its own currency, but this became more and more annoying as the Alliance got larger, eventually the First Galactic Bank of Castor was founded, and the TGC was created. Every world in the Federation accepts TGCs, and most worlds in the Pollux Imperium accept Trans-Galactic Credits as well.

The conversion rate for TGC to Irium is: 1 TGC = 16 Irium Strips
