History
The Galactorum was an arena created by the Grandmaster on the orbit of Battleworld to be used on his first Contest of Champions in Battlerealm.
At some point, Grandmaster left Battlerealm, wich eventually led to the end of the contest and the closing of the Galactorum.
Some time later, the Collector, who had been conducting a new Contest of Champions behind his brother's back, reopened the Galactorum to be used on the second phase of his contest.
