Sources for the Shadowfell

Hello!

Sooner or later the players are likely to find themselves in the Shadowfell on my current campaing.

Does anyone know of a great adventure or campaign set there? I'm looking for inspiration for challenges and places unique to the Shadowfell, and for what its inhabitants might want?

Thanks in advance 

Are they going directly into the shadowfell or do you have a certain place in mind? Like a Dread Domain. Curse of Strahd takes place in the Shadowfell, the Van Richtens Guide to Ravenloft also widely incorporates the use of Dread Domains in the shadowfell, there is also this city that is a parallel to a city in the prime material plane(the name for both I cannot remember) with sentient ghouls, necromancers, and other undead. As for monsters, the Sorrowsworn are some nasty creatures built on emotions such as anger and loneliness found in the Shadowfell, a boss would be a Skull Lord, pretty cool but not as cool as it was in the older editions. Some interesting NPCs might be the Shadar Kai or Measles seeing as how both are tied to the shadowfell. Perhaps your players went too close to the misty borders of a dread domain and got engulfed, or maybe they're traveling to this city. I think its just important to remember that anything on the prime material plane is mimiced by the shadowfell, especially if it's a place where great evil or betrayal took place.

The old 3.5 adventure Cormyr: The Tearing of the Weave has a long section that takes place on the Plane of Shadow (what the Shadowfell was prior to 4E).  You could look there for inspiration.

The Shadowfell was introduced in 4e, and while there's some adventures set there (P3, E1-3), they don't seem particularly well regarded (I don't have personal experience with them). There's also a sourcebook "The Shadowfell: Gloomwrought and Beyond" which seems a bit better reviewed, but it's for 4e which is going to limit what you can do with it.

In 5e, there isn't much other than Ravenloft (Curse of Strahd, Von Richten's Guide), which is pretty good for what it covers but doesn't tell you anything about the rest of the Shadowfell.

There's a DMs guild product 'Riddle of the Raven Queen' which seems decently reviewed.

I like to read through the Forgotten Realms wiki. It has great citations to use as reference points to find those old adventures or even some old Dragon magazines. 

I ran a heavily Shadowfell inspired campaign for my players and I can vouch that Gloomwrought and Beyond is an amazing sourcebook to give you ideas. As mentioned it is originally a 4e book so everything in it statblock-wise needs modded, but for setting it's a great help. You can find free PDFs for it pretty much everywhere with a google search.

I hope your players have fun with it! I know more than a few of mine left that game with some minor PTSD lol.

I'ma just drop this here.

Wooow muchas gracias , no conocia ese libro hombrew pero ahora lo necesito en mi biblioteca urgentemente

Besides the "Shadows of Sithicus", "Ravenloft: Horrors Within", "The Curse of Stahd", and "Van Richten's Guide to Ravenloft" books, which are all D&D products and all [as far as I know] within the sub-realm of Ravenloft;

"The Book of Ebon Tides"  a sourcebook published by Kobold Press is based in the Shadow Realm [Shadowfell]. It was released just a few months before this topic was first posted. It has different races and subraces, subclasses; new spells, 15 different Fey courts, 8 new realms beyond the courts, pantheons, monsters and magic items. Plus it has a fair explanation on the differences between the Shadow Realm and other realms.

"Tales of Shadow" an adventure also Published by Kobold Press 2022 is based in the Shadow Realm. 

I might also place the Dungeon Dudes' city of "Drakkenheim" within the Shadow Realm even though I don't think it is.

So, there are a number of books just from DND Beyond that would be useful for fleshing out the plane of Shadowfell.

We have been playing in Shadowfell for a while.   Here are the house rules we are doing.

We are playing that all conjurations are modified to undead.   Paladin summoned a Greater Steed and got an obedient, helpful Warhorse Skeleton.  That worked out fine.  But this includes food, so create food and water, etc. are not fit for eating.   Similarly wishes are granted but modified with an undead theme. (Wishing raise from the dead makes them a DM controlled evil vampire or similar creature, bad idea) 

If you fail 3 death saves, you become undead immediately.

When you sleep there is a chance that you awake exhausted. (save)

The cloud cover is lower (varies but never lower than 20 ft above us and never more than 100 ft).  The clouds are full of 100s of incorporeal undead that only attack you if enter the clouds.  Basically, flying is very limited.
