A link between eras.

But during the tournament, something went wrong... Suddenly, the mages were attacked by the Krigans... Few survived, managing to live only thanks to luck or their own strength... After that, the mages decided to unite against the demons, and the survivors of that tournament were put at the head of the armies... When the demons were driven back, a seal was placed on the exit from their domain, preventing the Krigans from leaving. And it was placed by a mage, who later became the king of mages. But the war sowed its seeds, and the sprouts were turmoil and discord among all.
It was then that necromancy was reborn, a science cursed by the living.
