Journeys Through the Radiant Citadel is an anthology of standalone adventures Dungeon Masters can inject into their campaigns or run as one-shots. The adventures take characters across the multiverse and include challenges for characters from levels 1 to 14. Each ties back to the Radiant Citadel, an ancient city found deep in the Ethereal Plane.

Co-lead designers Ajit George (writer on Van Richten's Guide to Ravenloft) and Wes Schneider (senior game designer for Dungeons & Dragons) lead a diverse team of writers, editors, and artists to bring 13 new adventures and 11 new monsters to life. Each adventure found in the book ranges in tone—from the whimsical to the horrific—and takes characters to civilizations yet to be discovered in D&D.

What Is the Radiant Citadel?

The Ethereal Plane is a hapless and misty realm that borders the Material Plane. Travelers who become lost in this immense place may stumble upon an ancient city built from a massive fossil that snakes around a gleaming crystal of impossible size. This is the Radiant Citadel.

Constructed by over two dozen civilizations of old, the Radiant Citadel serves as a beacon of hope for the lost, the displaced, and the inquisitive. The city functions as a throughline for the character's adventures, similar to how the library of Candlekeep served as a starting point for the adventures found in Candlekeep Mysteries.

What sets the Radiant Citadel apart from Candlekeep, however, is that it is setting agnostic. “Rather than just being a normal city, [the Radiant Citadel] is floating out there in the multiverse, in the plane that is forever one step away from reality. Pretty much wherever you are in the Material Plane, you have the ability to access the Radiant Citadel," said Schneider. This makes it easier for DMs to tie their existing campaigns into the adventures found in this new book.

From the Radiant Citadel, characters will travel to vastly different civilizations throughout the Material Plane that have been inspired by real-world cultures and mythologies. If they wish to explore the Radiant Citadel, DMs will have a gazetteer to reference that outlines the city and its peoples in great detail. Journeys Through the Radiant Citadel also includes gazetteers for other locations.

New Locations to Discover

Beyond the relative safety of the Radiant Citadel, characters will face challenges in unique locations throughout the Material Plane. No matter whether a campaign is set in the Forgotten Realms, Eberron, or somewhere else, each location presented in these adventures can be dropped in. This allows DMs to flesh out their favorite campaign settings with ease. Similarly, DMs will be able to satisfy different players' tastes, whether they prefer facing off in light-hearted contests or facing down bubbling unrest.

The 1st-level adventure in Journeys Through the Radiant Citadel is "Salted Legacy." Written by Surena Marie, the adventure is a comedic mystery that takes characters to the bustling Dyn Singh Night Market. There, they discover an intergenerational feud between rival vendors after mysterious cases of vandalism and theft occur. To solve the mystery, characters will need to earn the trust of those who work the market. To do so, they'll need to complete a series of challenges. "These challenges range from a spicy pepper eating contest to a timed cooking challenge where players have to battle and defeat giant prawns in order to make prawn patties,” said Marie.

Players with a taste for horror will enjoy Erin Roberts' 3rd-level adventure, "Written in Blood," which will have their characters investigating a haunting during a celebration held on swampy farmlands. Mario Ortegón's 5th-level adventure, "The Fiend of Hollow Mine," takes characters to San Citlán to investigate a magical disease and an owllike fiend that terrorizes locals.
