I'm sorry, Father. Not that I broke my vow. I'm sorry I didn't break it sooner. I never did fit in at this place. We both knew that. And now I'm making a new vow... Lucien will die for what he did to you. I won't break this one."
Appropriated Appellation: Nicknamed "Hammer," which she doesn't much like, by her fellow monks. When she renounces her vows, she takes the name for real.
Be Careful What You Wish For: She finds the life of a monk boring and wants to go adventuring. She does so, but only after her father is killed and she breaks her vow of pacifism to avenge him. At the very end, she declares she's sick and tired of violence and just wants to be happy again.
Drop the Hammer: She pulled it off a statue with her bare hands. It is BIG. And made of stone.
Gentle Giant: The Hero of Strength and sized accordingly, but originally a pacifist who chafed at her vows because she wanted to do more than pray to defend the well-being of others. Even after she renounces her vow, she remains firmly on the side of the angels. (And she's always pleased to see your dog.)
The Lancer: The first of the Hero of Bowerstone's allies and, by far, the most supportive one.
Last of Her Kind: Theresa mentions in Fable The Journey that Hammer was the last remaining member of a ancient Heroic bloodline descended from the Hero Stone, and that it ended when Hammer died of old age without children following the end of Fable II.
Pet the Dog: Literally. It's the first thing she does upon seeing him. Apparently the adoration is mutual.
Stout Strength: She is a very big lady with a very big hammer that she uses very well.
What the Hell, Hero?: She will call the Hero out if you choose the wealth option over your family or all the people who died.
Garth (Ron Glass)
Badass Bookworm: Oh yes. Garth wanders the world with a pack full of research, and is the foremost expert on the Old Kingdom and its artifacts. Oh, and he obliterated a fleet of ships with magical fire when he got "a little overzealous."
Ethnic Magician: The Hero of Will and from Samarkand, a faintly Asian culture (except with dark-skinned people).
Heel-Face Turn: He was working with Lucien at the start of the game. At that time, he had no idea he was on the bad guy's side—in fact, his first appearance is his walking out on Lucien because he realizes the latter is crazy.
Heroic Neutral: After escaping the Spire, he just wants to return to his research and evade Lucien. Theresa manages to convince him to join forces with the Hero and Hammer to put a stop to Lucien permanently.
Non-Action Big Bad: Lucien is killed rather unceremoniously in the end either by you or Reaver.
Cosmic Retcon: Though his original intentions with the Spire may have been to bring back his dead wife and daughter, he eventually realizes that the world itself was the problem. Of course, the Hero of Bowerstone prevents him from achieving his ends.
Start of Darkness: Lucien was a genuinely good and competent ruler before the deaths of his wife, daughter and sister. After that, his sanity very slowly begins to erode as his obsession with the Spire increases.
Unwitting Pawn: It's implied that Theresa manipulated him into rebuilding the Spire.
What? What is that? What are you doing? You think a mere trinket will save you? Do you think anything can? Stop! Think about what you're doing! I will put an end to chaos! Stop now, you fool! You insect! I order you to stop! Sleep! I command you to sleep! Sleep!
The Barnum: Subverted. Everything he does is on-the-level, and he helps a lot of people should the Hero aid him.
Delusions of Eloquence: Studied a horrendously inaccurate thesaurus to boost his vocabulary. Whoever wrote it hadn't the slightest clue what spelling was. It defined synonyms for nasty as 1: distrafolic, respinacious, aggravitising.
