Fifteenth Pius Dea Crusade

The Fifteenth Pius Dea Crusade was a religious crusade orchestrated by the Pius Dea cult against the Herglics, an ancient spacefaring species. In 11,660 BBY, almost fifty years after the previous crusade, the Pius Dea-controlled Galactic Republic launched an invasion of Old Barag.

Behind the scenes
The Fifteenth Pius Dea Crusade first appeared in the 2012 reference guide The Essential Guide to Warfare. While the Fifteenth Crusade is not mentioned explicitly in the text, the Crusade appears on a map of the Crusades and their movement across the galaxy.
