From the description:
The Festival of Lights is three days away, but the halflings of Hilltop Grove have a serious problem. The Fairy Tree and their beloved dryad have fallen ill. Without them, the festival is in jeopardy.
This 5e adventure is designed to be played by level 1 characters in about 3 hours depending on the size and experience of your group and how engaged they get with the social parts. There is a minimal amount of combat and an effort has been made to give options to avoid some of the combat while still giving them an opportunity to sling some dice and use their character abilities. If you need inspiration for the intended themes, look to Netflix's The Dragon Prince or Studio Ghibli movies like Nausicaa of the Valley of the Wind.
