From the introduction:
A sorcerer blasting his enemies with the power of his mind. A muscled barbarian wielding a flaming sword against the local tyrant’s thugs. A secret cabal of magicians plotting to control the minds and souls of kings. A gladiator who freed himself from slavery wanders the land, righting wrongs and smashing villains. Big muscles, big swords, eldritch sorcery, powers of the mind, eldritch beasts. From Burroughs to Howard to Moorcock to Italian Peplum films to those dreaming of outlandish post-apocalyptic worlds, heroes raise swords against corrupt nobles, inexplicable sorcerers, and alien monstrosities.
Sword of Cepheus allows you to dive right into these exciting tales and take the role of the heroes and anti-heroes wielding swords and sorcery in such settings.
