For every beast slain in the field, another was swiftly hatched to take its place and humanity was faced with a grim war of attrition.After a decade of bitter galactic conflict, it was all humanity could to do slow the advance of the swarm and with each passing year we came closer to extinction.The grinding cost of war mounted. The realization set in that without a radical shift in tactics and technology the forces of humanity would run out of soldiers before it ran out of bullets.In desperate response to the real threat of total annihilation, humanity created the Einherjar. Fearless new warriors with frightening new weapons who were sent to fight the wolves at the gate. less
