Grox Imperium

The Grox Imperium, officially known as the Collective Empire of the Grox and it's Subjugates was an intergalactic empire located within the Milky Way Galaxy.

At one point, it was considered the superpower of the galaxy, and at its peak was the largest intergalactic empire in history.

It collapsed during the Great Revolt, reducing the Grox people to a main planet with a few colony moons.
