StolenMadWolf
The year is 2020. Eight years have passed since the Retrovirus spread across the earth and ravaged human society. The lucky ones died horrific deaths. But most were changed, twisted into inhuman monsters called Ferals. These beasts tore cities and nations down, slaughtering, and infecting millions in their insane charge across the world. But they were not the only chimeric creatures to emerge. Other 'werewolves' had made themselves known, attacking humanity at every opportunity. Stronger, faster and tougher than the best of humanity, yet smarter and far more skilled than the Feral Hordes. The Nýúlfur. Pushed to their breaking point, humanity lashed out in hatred, if not in chemical, biological or nuclear hellfire, then by their force of arms.
Today, only a handful of cities and nations survive, amongst them, the post-apocalyptic country of Cascadia. But the Ferals continue to prowl the world, whilst the Nýúlfur to continue to fight both human and Feral alike out in the wilderness.
But things have started to change. One human survivor finds himself twisted and altered through immoral experimentation, leaving him an outcast. As he struggles to put what is left of his life back together, this survivor's newfound status gives him a unique insight into the world, and the true nature of the conflict between Humanity and the Nýúlfur. But soon, the mysterious Organisation that experimented on him in the first place will re-emerge. An Organisation with a peculiar connection to the Retrovirus itself...
