My Last Desire

Deep in the forest, you discover a dilapidated treehouse high in a giant old tree. It was home to a mystic from a faraway land. He had befriended Ravinnik, the Boggryn King, hundreds of years ago. When the mystic died, the Boggryn preserved his body in magical amber and now worship it as a strange idol. 

The Boggryn occasionally visit a mystical place deep inside the tree, accessible to mortals through a hole in the trunk. Will you dare enter their realm?

This faerie adventure is also part of my other TTRPG adventure - Night of the Gallowgrim.  It's system-neutral, so you can play with any rule-system you want!

System-neutral means there are no stats for encounters. This gives you freedom to use any numbers you want, making it scalable to any motley crew of adventurers and their skills.

The adventure also allows you, as GM/Referee, plenty of freedom. Apart from encounters, feel free to add anything you want. I've provided a list of possible Faerie creatures on the last page, but everything is just a guide. In the spirit of old-school gaming, you get to use all of this as a jumping off point for your imagination.
