The human empire - Cuvash, is at war at three different kingdoms that had banded together.

Kingdoms where the races and people of which, has an advantage over humans. Be it the advance weaponry of dwarves, the near unrivaled marine tactics of the MudMen or the nimbleness of the Cherims. Advantages that put humanity on edge before the three races had decided to fight under the banner of one goal- to take humanity down.

There is also the threat of the savages on the other side of the continent to their north.

Add on the fact that turmoil and mass hysteria had taken over the minds of their people- the current rulers of humanity spent staggering amounts of resources to ask their gods for help.

And they delivered- Five heroes with knowledge and tactics from their more advanced worlds were summoned to aid humanity and save them from peril.
