From publisher blurb:
An Advanced Class for the Galaxy Command Campaign Setting
Magno-Star is the hottest sport of the 35th Century- a fast-moving, thrilling, three dimensional combination of soccer and rugby played by technologically enhanced magnetic manipulators. The first Magno-Star leagues started up during the 32nd Century, by bored ore miners on the remote colony world IronClad.
The four hundred day planetary night on the remote mining world was long and arctic, but nothing outside the tolerances of the tough, cyber-enhanced colonists. What 32nd Century cyber tech couldn’t fix, though, was boredom. When off duty, the colonists needed something to keep their minds occupied: the local VR chambers got old after a while, and IronClad was too remote for regular imports of booze. So the miners found a disused shaft, and refitted their work-suits and cyber-implants to have a little fun. A few thousand bruises and broken bones later, actual rules were laid down.
Today, Magno-Star is a multi-trillion credit sport. Every world in civilized space has a local team, and virtually every citizen of Galaxy Command bets on big matches. The sport of today is fast moving and high tech, and its supped-up stars are revered as some of the galaxy’s greatest heroes.
