Laconic:
Adventurer's Tavern will help you to create an establishment, whatever the genre might be, where you might typically imagine a party of 1st-level adventurers might start out on their campaign. Works really well when working towards a theme or setting, though as it is with many models, creating specific characters in the scene may require inpainting or other means.
Loquacious:
This LoRA was trained on a ton of different images with adventurers of all sorts, from fantasy to sci-fi, gathering at a watering hole of some kind or another. Sometimes it will do an excellent job of creating a number of unique individuals in the generated image, but other times it will insist on creating what must be a bar for clones. This can sometimes be a matter of the prompt, the base model or even a particular LoRA you're using along with it.
The most direct solution for this, I've found, is making use of inpainting, making the first gen serve as an initial template if you've got a certain vision based on the result. I wanted to have two members of a sci-fi adventuring party blowing up at each other, and a little inpainting let me do that with little effort now that I had the players set up around the table, as it were:
The cyborg is totally throwing the guy on the right under the bus.
This LoRA is also just fun to play around and experiment with with other LoRAs that change the style and setting of an image, really giving a dramatic change to the environment without much effort. And on the subject of prompts, you can start off with something as simple as:
meetmedere, fantasy tavern, 2boys, 2girlsOr whatever kind of tavern/bar/guildhall and quantity of people and build from there.
It's not going to be laser-focused accurate - it's going to build you a bar with a certain kind of vibe you're going for, with some playing around. But if you want a strong base for creating a scene at a tavern, or just want to experiment with how different taverns would look with just a few changes of some prompts, then this is for you.
