About Birthright

Birthright is a Dungeons & Dragons campaign setting that was first released by TSR in 1995. It is based on the continent of Cerilia on the world of Aebrynis, in which the players take on the role of the divinely-empowered rulers, with emphasis on the political rulership level of gameplay. The setting revolves around the concept of bloodlines: divine power gained by heroes and passed on to their descendants. Characters with a bloodline create an aura of command known as Regency, which is measured in the game using regency points or RP. Using regency, characters acquire a domain composed of provinces and holdings. The development of these domains is as much a part of the game as development of the characters. The game uses three-month domain turns to model actions of rulers over nations in much the same way as Dungeons & Dragons uses combat rounds to simulate time to model the characters' actions in battle. In 1996, Birthright won the Origins Award for Best Roleplaying Supplement of 1995.
