A high-fantasy world on the verge of a technologic/magic synergized breakthrough.
Unfortunately the world isn't so simple, nowhere near the usual one-kingdom-versus-the-other, and many little islands and kingdoms refuse to cooperate with the breakthrough, or even oppose it together with conquests.

As is the norm with revolutions, many lands and countries dissolve, or even turn into greater, stronger countries and kingdoms.

There is no overlying 'main setting' here, and you will find that many of the characters quite possibly will never come close to interacting, though they all occupy the same era within this world.
