There's only one way to Cinderbrick Fort, the hard way. Sure, the City Marshals may be gone, but now the Fort is crawling with Windbags.
The Calamity was a mercy for normal folks. The Windbags ain't so lucky. They've been left to freeze or starve or face the Kid. Well, Windbags young and old keep fighting for the Fort. Windbags ain't much different than normal folks. All they wants a warm place to stay and a decent meal. Good thing the Windbags don't know Kid's fresh out of health tonics. The Calamity drove the Windbags topside. A lot of them wound up here in this very Fort. Could have been minding the business underground, like in the old days. Windbags can't use the Marshals' supplies but the Kid sure can.
