Cape fight in Baltimore, spring of ninety-four. The Pugilists versus the Grey Gang, and visiting Tinker Intricate using the entire battlefield as a testing ground for some of her weird things that she'll never otherwise have an excuse to deploy.
Intricate's spider robot hits a Shaker field and a Striker fist at the same time and everything goes white and red.
When the dust clears, only a Pugilist Brute and a Grey Gang Changer are alive, let alone standing, and also six square meters of another world have been switched in for some of the storefront of a Dunkin' Donuts and a bit of parking lot.
