When an impoverished noble discovers a royal birthmark on a wastrel poet and playwright, he immediately knows what it means: It means that he has a way back into Baltan high society, coat-tailing on the mysterious Prince's fame as deposed Royalty! Unfortunately for this patron of the arts, there are political forces who would see his protégé dead -- and other political forces who would use him as a figurehead for a Royalist Counter-revolution! Enter the player-characters, as friends or associates of the poet or his patron, caught in a web of intrigue, assassination, and violence: the dangers of the Blood Legacy of Mars!
