D&D Next - 5e Discussion

Hmm gotcha. If it's a place for activity and you already have stuff in mind for the headquarters, you could theoretically copy and paste what the HQ has and just trim things off as you like. Otherwise, here's my two cents. Feel free to include what you need and leave off what you don't.

1. Sleeping areas. Maybe a whole section dedicated to barracks, or maybe just a couple mattresses/cots/sleeping bags in a corner.
2. Restrooms.
3. Tables and chairs, or at least places to sit down and be comfortable.
4. Games of chance. Maybe some are scams, maybe some are legit, most are just for some R&R.
5. Depending on size, a stocked bar with a bartender. If it's too small, maybe some guy specifically selling booze and nothing else.
6. Fences buying and selling illicit goods, whether stolen or just outright illegal. You mentioned drugs earlier but (again depending on size) a black market here would encompass all that and more.
7. Along the same vein, maybe someone selling tools of the trade. Rope, lockpicks, small knives, crowbars, etc.
8. A kitchen, or at least a place where food is made. Maybe just simple stews and gruel for people who are hungry, or maybe fucking Sanji and Gordon Ramsey are here serving up 10 star meals for no reason.
9. If there's prisoners in cells, then there's guards tending to the prisoners. A guard post, or some such.
10. Maintainers. Essentially, people who watch over the place and take care of it. Maybe they clean and dust everything, cook food, manage the bar, guard the entry points, referee the market, do conflict resolution, etc. Or maybe they're just there to keep track of who comes in and who goes out. Or maybe there aren't any and people are expected to pick up after themselves.
11. Crates and barrels. More generally, space for storage, or if not a separate space, containers scattered around.
12. Along the same vein, maybe a dedicated locker room, as in a place where people can safely store things without fear of it getting stolen. Maybe they trust it to the maintainers who handle the keys, or maybe they hold the keys themselves, or maybe there isn't a safe place to store stuff because everyone's a thief, or maybe everywhere is safe because the guild's rules are that there's no thievery allowed in safe houses, and anyone caught doing so is punished.
13. Less of a "thing" and more of an idea. No keys whatsoever. They're thieves, they just pick the locks closed and pick them open when needed. If there's no keys, then there's no threat of the prisoners stealing one, and if the prisoners are good enough to pick the lock to their cage, then shit they're good enough to join the guild.
14. A bard. People like music. Doesn't have to be a professional either, maybe someone plucking a few strings on a guitar to lend some ambiance.
15. Corrupt officials doing business.
16. Guild officials. Might fall into the category of maintainers, might not. Someone with authority who's here to answer questions and watch the place.
17. People offering services. Bodyguards selling protection, thieves looking to join a heist for a cut, professional lockpicks offering to crack open really hard locks, perhaps a mage or mages selling magical services like spell casts, enchantments, potions, etc. Maybe sex workers, assassins, ruffians who will harass or beat someone up for cash or get beat up to make a scene. Guides who know the undercity like the back of their hand, or underground performers on a bad turn. City officials or guardsmen open to bribes. Maybe these people aren't advertising and are just existing in the area, but can be spoken to and hired.
