Tales of the Second Citadel is a high fantasy series focusing on the Second Citadel, a city-fortress surrounded by monsters. It is primarily told in the third person from the perspective of an ensemble cast.
Unlike the Juno Steel stories, the world of the Second Citadel is one in which prejudices against gender, sexuality, and disability are still prevalent, and a number of the stories deal with the characters struggling against those prejudices.
The Western Wastes is a land of "beauty and blight enmeshed". Its many rivers flow over the edge of the world. It is in a state of constant fall, with red leaves falling from the omnipresent Everdeads. It is home to the Garden of Graves and the Glass City of Gullwa.
The Southern Frosts is a cold and mountainous region with several small towns like Chillblains and the village of Drift. It was home to the camp of the Witches of Hiberna next to the southern sea.
The Wayward East is a land that was once full of verdant life but is now a vast desert full of violet crystals. The desert is called the Mirrored Plains. It is home to Silvershore, a secluded city with over a million residents where humans and monsters live together peacefully. Surrounding Silvershore is the The City Beneath in a freshwater sea with a silver beach that has anti-magical properties.
The Center of the Universe is a place where all four regions combine. It shifts climate between the four regions at regular intervals. The Undersea Palace lies nearby.
