@Lugubrious What does the Barge look like?
For your convenience I can include the information about it here for you. I'd always encourage reading posts of mine that concern the area where your character is in order to pick up on the worldbuilding!
Most impressive among these points of interest was a two-story structure with mining equipment attached to either end, almost more like a barge than a camp. It housed both black market traders and a gambling hall to those in the know, but to Omori it just looked like a miniature citadel of painted wood and rusted metal. With armed guards on patrol, he probably ought to steer clear.
The bar and weapons shop would be rooms inside. The Barge is more of a bandit hangout than an establishment under the control of a unified group, so causing a ruckus inside wouldn't aggro everyone; they'd be more likely to mind their own business. There are some armed guards around, but there are always clashes among outlaws so they'd only act defensively on behalf of their VIPs. Oh, and despite the image, it's on a rocky hillside, not in a swamp.
