The Dryad's Sanctuary is a short adventure from
Brian V. Molina, the first one from him, at least on DTRPG. Although apparently meant for OSR games, it seemingly uses a more modern conception of the dryad (rather than the old school sexy chick living in a tree), as well as stats that don't seem particularly compatible with anything, though it does seem to use the reverse reaction tables from Labyrinth Lord (where higher rolls are unfriendlier).
The basic premise is that the PCs have entered this magical wood ruled by the dryad. The only way out is to kill or negotiate with her. But first they have to find her, by wandering through the forest. And I really do mean wandering, as there is no map, the players just go to the different encounter areas by random chance (roll of a d12). Mostly. There's one area that is connected to another.
