In the Great Catastrophe, Humanity lost its war against Demonkind, and now the remains of their civilization dwell in broken villages, or in empty caves. But even so, there are those who have refused to let the world die so soon, and one has even betrayed Hell to redeem this world. As the days grow short, and eternal night draws close for this world, the wavering will and strength of humanity is all that's left to combat the end. A Grail waits, the Vortex rages, a Prince rises, and the Phoenix rouses from the ashes.
