Build on what you've got
Think through what you know about this site. What can you assume from context? What have you told the players and what have they told you? What have you already decided, in your heart of hearts?
If there's a resource that you want to build on or adapt—like an image or map, a module from another RPG, or an adventure starter—think about that, too!
Why are you putting this site in the game? For color? To break up a journey? Because this is where the PCs can find what they're looking for? Or what? Do your reasons imply anything more about this site?
If you're prepping in advance, then write this stuff down. If improvising, just think it through. Either way: let your creativity build on this foundation.
I jot down what I know about this site:
- 1½ days away, in the Great Wood
- Sajra's been here since last fall
- Sajra displaced a Fae squatter, Thornthumb, who's still in the area and holding a grudge
- Sajra has entranced a nest of crinwin and two Stonetop children
- Crinwin are looting a nearby ruin to add to Sajra's hoard
- Rhianna was here in her youth
- Forest Folk left burnt offerings (?)
I'm putting this site in the game because I need a lair for the villain, and because I'd like the PCs to meet a mummified Green Lord, maybe. Which tells me that:
• The tomb is basically intact
