My PCs are pursuing a major villain who deals with assorted plant-based monsters, who we'll just call the Queen. Being a manipulative sort, I think she would probably try to lead them towards attacking the local druids, who are naturally in conflict with her. However, I'm at a loss for how she could actually accomplish this. Some of my ideas so far are:
Hint that another NPC (a certain PC's mother) has been taken into custody by the druids, when the Queen actually has her.
Simply claim to be a part of the local druidic order herself.
Point out that the druids oppose construction of the major city in the area (to which several of the players are associated).
However, I don't really feel like any of these would work. The first seems the most likely, but that PC's player has been struggling to show up to games and none of the other players are familiar with her mother. (I actually don't have anything about the other PCs that could be useful here — the ranger doesn't get along with anyone in his backstory, everyone the thief knows is dead, and the priest gave me nothing.)
I'm running AD&D (2e) and building the world from the ground up, pretty much as we go. This particular druidic order resides in the continent's largest forest, where the Queen has been making her base of operations.
So, what would be the most effective way for a mid-level spellcaster to draw a party into conflict with a druidic order?
