About
The sun turned black, the earth sank into the sea, and the twinkling stars vanished from the heavens. Fierce flames enveloped everything, scorching even the sky.
Surtr came from the south, bearing the fires of calamity. Bringing despair in his wake. Livestock and families alike all perished.
That was when Valhalla rose. Valhalla created the Battle Maidens. And the Battle Maidens, carrying the souls of brave warriors, took to the skies to strike down Surtr.
From "Understanding Valhalla's History," published by Yggdrasil Corp.
A parallel world that followed a different future from our own. Suddenly, "Fire Giants" appeared in the world. These giants drove humanity to the brink of extinction. The few survivors named the giants "Surtr" and created weapons and an organization to counter them. This is the story of the warriors who fight Surtr and the doctors who support them.
