From the back of the book:
There is an energy in Théah.
A great power summoning forth the brightest souls, and the darkest. These are the Heroes and Villains of Théah. For every knife-twisting assassin, there is an ever-diligent bodyguard. For each great act of courage and hope, there is a dastardly deed performed in darkness. For every Hero there is a Villain.
Théah is a land of great evil...
“As time passed, she began to speak to the darkness...and it began to answer. The darkness became her friend, her mentor, her confidant in those times of hardship.”
…and even greater good.
“Whether it was diving into heart of a tempest to rescue a crewmate or fending off a dozen pirates single-handedly, he met every challenge with fearless mirth.”
The 7th Sea Heroes & Villains book gives you 40 Heroes and 40 Villains to use in your game. It discusses heroism, villainy and possible redemption for lost souls who have fallen into darkness and includes new Advantages, Backgrounds and other systems.
