Here is a quote from the press release:
Once upon a time, there was a group of mages – powerful sorcerers who used their great spells to control cities and tame the wilderness. But wizards are naturally interested in the betterment of all humanity, so one by one they came to the conclusion that the world’s problems could be solved if there was a single great mage – one warlock that could direct the affairs of all men and all other wizards.
Of course, the only way to settle who should rule this land was by a great test of magic. And armies and catapults, of course. The road to magical harmony is littered with the bones of those that would not listen and obey.
