The Reckoning

The Reckoning is a massive tournament that takes place across several different Realms within the Omniverse. The Reckoning itself was first formed by early members of the Military Orders, but in time expanded to include all the Orders (or at least those that were willing to participate). 
The Reckoning is a massive contest between teams of Adepts who are assembled to represent their Order against the others. The Adepts must fight in contests, the nature of which is decided before hand by Prefects who seek to devise ever more ingenious games to pit the constituent Orders against one another.
