Black Blood Battlefield

In the world of Black Blood Battlefield, blood itself has risen from the soil. Ten years ago, the ground itself sank, across the globe, bringing blood out to the surface and into the public view. Energies unknown to science, magic, rose forth and races of parallel dimensions, mentalities, and alien knowledge were trapped with us. The sky itself, rained blood, and turned a hue of red. The sun shifted towards a blue, and dwarfed the sky in it's inferno. At night, the stars went missing, with only two moons to guide us... Some doubt we're even still on Earth, and the aliens didn't come to us. Others say many worlds were collided together... we all know that

What are you? You are a Black Blood Battler, someone's who's blood was tainted with dark magic, and now gathered to fight the evils that lurk within this new, ghastly Earth. You utilize your blood itself as a weapon. Losing too much will put you out, but it'll punch harder than any gun. You fight within the city of New Alexandria, built over the ruins of a newly risen Atlantis...

Races:

From the seas of blood, new races came along with the monsters. Many are discriminated against, however they all bring something new to the table that they can  utilize in and outside of combat.
