Due to its enormous size and high density, Megalox Beta generated a gravitational pull ten times standard. Outside an artificial standard grav-field dome, anyone walking on the surface of the planet would be instantly crushed under ten times their own weight. The only settlement on the planet was a prison called Megalox, which was protected by a gravity shield generated by an orbiting space station. Megalox was home to some of the worst criminals in the galaxy. One known location inside the prison was Grakkus’ fortress.
