This is a campaign idea I have which is that the PCs get hired to work for the Ravenloft Cartographer's Society a group that is trying to map the many realms of Ravenloft.
The RCS give the party a Mist Compass that allows them to travel the Mists of Ravenloft to traverse the Nightmare Realms therein. This campaign will be much more designed around the group of characters themselves.
Welcome to the Jungle! A death curse has befallen everyone who's been raised from the dead. Its victims are rotting away, and all efforts to reverse the decay have failed. The douls of the dead are being stolen one by one and trapped inside a necromantic artifact. Only its destruction will free the trapped spirits and allow the dead to be raised once more. All paths lead to Chult, a mysterious land of volcanoes, jungles, and the ruins of fallen kingdoms. Below them all awaits a deadly tomb. The trap is set. Will you take the bait?
Magic has stopped bringing people back from the dead, which will have impacts on the players and this adventure is described a "meat grinder" in the front of the book, "suitable for experienced players who have highly optimized characters and who don't mind putting those characters in jeopardy for the sake of a good challenge. It is less ideal for players who are inexperienced or get anxious at the thought of losing their characters." What does this mean mechanically? A death saving throw only succeeds on a roll of 15 or higher (instead of 10 or higher).
Pendelton Ward was one of the Story Consultants on this campaign so despite it's deadliness, there's a lot of silliness to this adventure that I am really excited for. It will be either monthly or biweekly and will be run online. React if interested in being added to the discussion & planning.
This is said to be one of the most fun campaigns for both players and GMs. Most of the people in this server play more D&D than most and so are at a higher skill level than most of the books. This one is made to specifically challenge those types of players. This one will feel dangerous because the rules about dying are tuned towards making the campaign more lethal than most. Pendelton Ward (creator of Adventure Time) was involved in the writing of the campaign so it has just the right amount of wackiness for the high lethality of the campaign itself. Also there's images of undead dinosaurs and thats just fucking cool!
