Try these druid-centered adventures.
The druid is approached by a female bard who loves a Shapeshifter druid. While she worked in town, he spent too long in the form of a bear and became trapped in that shape. Worse, hunters captured him and sold him to an arena, where handlers will force him to fight other animals (or humans) to the death. The games begin in a week. The bard beseeches the PC--the nearest druid--to help her free her love.
A dryad heard that a group of pixies is tormenting a green dragon--playing tricks on it while invisible, stealing trinkets, and the like. The dragon can't find the ones responsible, and the dryad fears its rage will devastate the wood. Someone must tell the pixies to stop--and calm the dragon down.
While hunting a stag in the forest, the king's youngest son was killed by a great wolf. The grief-maddened monarch has decreed that every wolf in the wood must die, enticing hunters with a bounty of 50 gp for each pelt. What should the druid do?
A young elf and a human ranger love each other, but their parents do not approve. They run away to the woods, begging the druid to marry them. But the angry parents are not far behind . . .
A strange blight is afflicting the forest, turning leaves a luminous white. The druid must discover this disease's secrets before all greenery disappears from the forest.
Someone has stolen a sylph's egg! She left it only an hour to visit her nymph friend. Now, heartbroken, she asks the local druid for help. Suspects or witnesses in this forest whodunit include a flighty pseudo-dragon, a pool of nixies, a jealous aerial servant, and a drunken satyr.
