Say a Prayer for California: Sister Cities

Sister Cities is set in post-apocalyptic Kansas in the year 2014 and focusing on a group of artists and assassins. In this campaign we use the standard DnD mechanics and classes (and more than a few homebrew classes), but all of the "magic" has been translated to real world technology and your "spells" are typically programs run in an augmented virtual space on small, handheld devices. In this universe there are fashion designers, evergreen artificers, a corrupt military police state, patron saints of the apocalypse, a voice on the radio, and a chance to save the world, or at least your little corner of it, with art (and potentially explosives).
