The party's in the tavern. They find out about the local dungeon. They get to the dungeon. But what about that travel in-between? There's a whole wild world out there that they will travel through. If you're looking to add more atmosphere and excitement to your game's environment besides the various set pieces, you'll want to check out Into the Wyrd and Wild: 2nd Edition, an RPG supplement that's up on Kickstarter now.
From the campaign:
Into the Wyrd and Wild is a supplemental book for those seeking to incorporate a weird and terrifying wilderness into their role-playing game. Players and GMs who enjoy a level of horror and prefer the sweeping, darkened landscapes of forest and mires to the well-trodden cobblestone of dungeons need look no further when it comes to books. Presented within the book is a light overhaul of the adventuring system, modified to fit better with a campaign centered around forays into the frightening wilderness.
In addition to stocking the area with new monsters and set pieces, Into the Wyrd and Wild is also an attempt to increase the playability of the wilderness. Rather than have the wilderness remain a place along the way to a dungeon, it seeks to make the wilderness a dungeon in itself. Included in this is an essay on design theory as well as a way to easily and randomly construct a wilderness dungeon.
The campaign's about 3/4 of the way to its goal with 23 days to go.
