From Back of the Book:
For countless millennia, Mecatol Rex was home to the mighty Lazax, rulers of the known universe. Other empires rose and fell. Other civilizations reached the stars, then flickered out. Yet Mecatol Rex shone on, a gleaming star in the crown of the Lazax Imperium.
Even now that the Lazax are gone, Mecatol Rex remains the center of power in the galaxy. Emissaries from the Great Races continue to meet here in the Galactic Council, forging agreements, deciding policy, choosing the fates of millions of beings throughout the known universe.
Mecatol Rex is full of mysteries. Very few know what lies beneath the surface of this once-great planet. Fewer still know the truth of the whispers coming from its hidden depths. While the Great Races strive to control the galaxy, the legacy of the Lazax lies just out of sight, full of power and danger.
