D&D 5E Pick three big adventure books and mash them together for a new campaign

[HammerMan]

Take three big adventure books and mash them together for a new campaign.

curse of strahd (Dark, has a great BBEG, and has a goal even if the PCs don't know it at first)
Strixhaven (connections matter, and mixed with the needing alies of the above works really well)
Sunless Citedel (It's low level, it has a town and a dungeon, and you can make enemies into allies)

scrub off all the serial numbers...

there is a dark lord (I'm making mine a Ghoul Queen instead of a vampire) she rules over a small bit of land (I'm going with valley... I don't know how I would force PCs to stay maybe do the mists of ravenloft but maybe just do 'its the game') and within in she rules allufly. There are a handful of towns each run by there own lord mayor or counsel... only 1 is safe at all with awall self contained with something living in the old abby (Instead of a corrupted deva I am going to do redeemed demon... he is chaoric good and trying but he has to stay mostly hidden). none of the cities has a large force, just some few guards... but they all work with the red tower.
The red tower is an academy to control magic... people who have smarts and want training, people born with magic, and even people who cut bad deals and have magic all go there eventually to learn to control there magic... PCs start at or near the tower...

the ghoul queen doesn't rule from a castle on high... but deep in the ground, a sunken city... years ago an earthquake sent a village into the underdark, it is now the seat of the ghoul queen and her consort the lord of the goblins... but the goblin lord is at war with the kobolds that are in the caves nearby... and those kobolds have there own queen a half dragon kobold sorceress and her 'half brother' a wyrmling white dragon.

ghoul queen is a lesser agent of Orcus.... and as such the end goal is to overthrow her, but you need the divination teacher at the tower to look into your fate and read where the alies and weapons you will need are... oh and the Ghoul queen LOVES messing with people... and sometimes taking in people for dinner (and she doesn't even always eat them)

the final exam of this game isn't pass or fail... it's do or die.

Rime of the Frostmaiden
Descent Into Avernus
Tyranny of Dragons

Frostmaiden start. Dark world, dark times. Find clues that Auril is being supplemented by devils and white dragons to bolster her magic to regain her divinity. Learn that she has a contract with Asmodeus in order to become a Greater God again — the Goddess of Fimbulwinter. Also find that frozen city, and have clues all around it that it comes from another land, the people just disappeared, and that some kind of sacrifice happened here.

Players finish the job, lead the North. They go to Baldur's Gate, something comes with them. Trigger DIA story. In this story, the tale of two cities is Baldur's Gate and the Frozen City, who will soon be sacrificed. But instead of being sacrificed to Auril, it will be sacrificed to Zariel, who needs these souls and this sacrifice to turn the tides of the Bloodwar for the next 10,000 years.

This leads to hell, and the Tyranny of Dragons. Cult of the Dragon gets the players into Hell, maybe lots of people into Hell, because they have a draconic oracle who has foreseen that someone entering Hell from Baldur's Gate will be what saves her.

Players get into Hell. Deal with all the Hell stuff. Have to save Tiamat. Once Tiamat is freed, now she is naughty word up the world, getting ready to fully manifest in the Prime Material Plane to claim it once more as her lair. The entire world, all creation: her lair.

Now its time for the Tyranny of Dragons. Take down the rising dragon empires, make use of demons and devils and frost naughty word to turn enemies against enemies, etc etc.

A Dark Fantasy Epic.

Levels 1-8: Frostmaiden.
Levels 8-15: Avernus
Levels 15-20: Tyranny of Dragons

Into the Borderlands (Just finishing it)
Castle Amber (Have been foreshadowing it)
Expedition to the Barrier Peaks (Just ordered it; might need a bunch of henchmen?)

The set-up is non-demi-human characters in a cross between standard D&D and The Dying Earth. (They've seen an NPC with an eye of the overworld riding an Oast, ran into a Deodand and know there's a Pelgrane somewhere [ both of those thought to have been extinct ], and have seen something written about the vats for making copies of people).

So the OP doesn’t specify that it has to be WOC hardcovers so I’ll say

Dragon Heist
Dungeon of the Mad Mage
Curse of the Crimson Throne by Paizo

All the power groups are introduced in Dragon Heist and in that treasure is a crown that is taken by Laerl and that possesses her.

The campaign then morphs into Curse of the Crimson throne with Waterdeep as a background as Laerl becomes increasingly draconian. Replace any dungeon delving or trips outside the city (Scarwall for instance) with trips into Undermountain.

Keep the powerful villains from Dragon Heist involved, maybe they hold the secrets to freeing Laerl from the curse or do they need to ally with them to defeat Laerl. Even Hallaster may get involved to save the city.

For even more Realms Lore, do a retcon and make the artifact the Crown of Horns, that Laerl really did get possessed by in her past.

The Adventure in the Mythic Odysseys of Theros
Witchlight
Storm Kings Thunder

Adventurers from Theros are exploring the Dakkon Ilses, having explored most of Theros & it's underworld, and after finding many strange wonders on various ilsands, they come upon an Island with a strange festival calling itself the Witchlight Carnival.

After enjoying this strange "carnival" they and their now enchanted to fly ship, are pulled into a strange plane called the "Feywild" far outside of their understanding of the cosmos.

After exploring the part of the Feywild called the Domains of Delight, they find themselves magically expelled to the Prime Material plane on a World called Toril when they begin to explore a region of that world on a continent called Faerun, a region called the Swordcoast and the North. From Evermeet and the Moonshaes, to the Kingdom of Hartvale to the wonderous cities of Neverwinter, Waterdeep, and Baldur's Gate, they eventually find their way to the underwater Realm of the Storm Giants.

Spelljammer
Radiant Citadel
Waterdeep: Dragonheist

The players find a Spelljammer during the events of Waterdeep: Dragonheist and during the events of the Spelljammer adventure they find a shattered field of crystals in the Astral Sea. At the heart of which is one that takes them to the Radiant Citadel. I wan't to mix and match events and even set some elsewhere but have them as part of a larger story.
