Venture into a realm of classic high fantasy with this extensive hardcover guide to six key countries of the Inner Sea. The Radiant Kingdoms are home to noble knightly orders, proud ancient cultures, and dangerous courtly intrigue. Explore Andoran, a bastion of democratic governance and freedom for all; Druma, a commercial hub passionately pursuing material profit; the Five Kings Mountains, hosting fractured dwarf kingdoms; Galt, a land torn by violence and revolution; Kionin, the home of elves shrouded in illusions; and Taldor, the skeletal remains of one of the most powerful empires of the Inner Sea. Each country features an in-depth history, a geographic guide, and a glimpse into a significant city to support a wide variety of adventures.

Each region also offers new character options, including archetypes, equipment, magical items, spells, animal companions, and more! In addition to these new options, characters can also learn about and engage with important local factions. These include the honorable Native Knights of Andoran, the steadfast defenders Shieldwrought Striders in the Five Kings Mountains, the demon hunters of Kionin, and the Lion Blade spies of Taldor.

The book also includes a bestiary of monsters inhabiting the region and an impressive fold-out map to serve as a central point in any Radiant Kingdoms campaign.
