Hi Devlin, Shadowfell...primarily undead, ghost and the like type encounters, and a rift between dimensions/worlds...correct? (If I have the gist of this incorrect, please forgive, but here are some ideas): Lessee, from the marketplace there is now so many goodies to choose from, but here are some thoughts of styles that might work well together: Overview map or world map : - R. A. Hapke's Old World Style might work: Old World Style Maps - and some combination of several of those sets. Close up maps: Outdoors: Gabriel Pickards Swamps 2 , or some of his wilderness sets would work well for outdoor encounter Philip Wright's Dark Village looks like a great perspective Melanie Paterson's Jungle Foliage is excellent for adding great hiding places when the dimensional rift brings in the Amazon. Need some traps? Shaun Ellis has some fun traps to throw about the map Joshua Kurz has some effects that would work well with the Shadowfell dimensional concept. And thank ya Alex Carmichal for making some pretty spiffy explosions Indoors: Stephen Shomo's Dungeon Connect for on the fly. Great shading too! R.A. Hapke's Castles is pretty lego style Greg Tayler's Dungeon Blanks Andy Gerding's Citadels has some great ruin tiles Sometimes, Gabe's slumming it beneath the city. Or for a cleaner sewer, Sean Archer has it covered with this set wanna keep with the isometric view? Plexsoup has some fun sets. His dungeon tile set Need some ruined statues? Gabe's vile tiles has some of those And if you want to push a bit more into the feeling of an extradimensional rift bringing in odd temples, Rhyannon's Mayan temple would be great. Tokens : - Brass badger has some great undead minions Devin Night has some fun Demons to toss in there. Nicky G's Steampunk inventions might be an interesting mix to add as well. Grae also has some undead minions if you want a different perspective. If cute can kill (which, after playing Dungeon world and almost dying by their hand, it can) Paul Ooshun's Dungeon Buddies And, doesn't every game need some good ratmen ? Thank ya Devin again! Although they're marketed as Desert Creatures , Jan Loos has some designs that might fit right in. Alec Thomas has some unusual other worldly creatures too. Puzzles : Dunno if you are needing anything puzzle-ish, but some ideas: Paul Camp's Rune Puzzles R. A. Hapke & D. Wolters: Ancient Scribe rock art Stephen Shomo's Dungeon Puzzles Just suggestions Devlin and hope they help with ideas. The nice part is, the majority of artists listed have multiple sets so you can get a lot more ideas as well.
