As I remember correctly, the scenario we had panned out was 60 years after the fall of the Black Dragons, my grandaughter finds my old war chest in the attic and reads through a journal cronicling the history of BD and FF from before the outbreak. Fairview, as well as Nastya's, is now run by the coalition of clans that took down the BD. My decendant brings the book to elderly surviving BD agents (Viktor and Tratpan) and they gather the descentants of the Black Dragons into DUSK, living on the outskirts of Fairview. We not only have to fight against the coalition that took us down, but the occasional zombie (sometimes created by us to add some chaos and panic) as well as the mysterious figure trying to plot our downfall (Mutant Modem, angered that none of his comrades came back to look for him).
