The City of Arches: A high-fantasy city sourcebook for D&D and other fantasy RPGs Paperback – July 4, 2025

Two thousand years ago, a tyrant of unimaginable power conquered a city on a site of powerful planar magic, letting him build portal archways to hundreds of worlds he intended to conquer. A thousand years after his defeat and exile, all remnants of the tyrant, including his very name, have been magically washed from history. The extraplanar archways this Nameless King built are mostly dormant now, but beings still sometimes step into the city through one of these archways, usually with little memory of where they've come from.Today, the city is a bustling metropolis filled with people of many races, species, ancestries, and heritages. Yet in the depths and outer reaches of the city, secret cults sense the void where the lost tyrant once ruled, and seek to bring the Nameless King back to power.City of Arches is a high fantasy sourcebook compatible with D&D 2014, D&D 2024, other 5th edition variants, and other high fantasy tabletop roleplaying games.
