Root is an asymetrical board game of factions trying to control a forest. It has a companion PbtA RPG based on the setting.

I think playing a session of the boardgame to set up the beginning state of the forest, and then running the RPG (with some Blades in the Dark faction tracking) would be fun.

Alternatively, run the RPG side with Mausritter. Make it more about delving into the deep woods and breaking into faction keeps.
