In the fictional BattleTech universe, the Lyran world of Solaris VII has become known as the gaming world, due to the gladiatorial battles held in the arenas of this planet, between MechWarriors in their BattleMechs. These fights are broadcast across the Inner Sphere via ComStar's network of HyperPulse Generator transmitters, for the entertainment of billions, in addition to those who pay to view the duels live. Solaris VII combats are the de facto sporting event of the 31st century.
