This one surprised me, and I'm struggling with it. Though we have had to walk through forests at some point in almost every campaign, they have never been the focus of any adventures. I'm not sure why. We've had adventures in jungles, deserts, mountains, and just about every other biome. But the forests are neglected. The only time I can remember them playing a part was in media res, when the party was being chased through the forest by another party. That was an epic scene, but nothing other than that. I'll have to rectify that with this brought to my attention!
