Main Character
On Lena's behalf, you go to the apothecary to purchase charms to hang on the scholae's doors to ward off soldiers and meet Locusta. She immediately knows you are of the Catauni. She tells you that if you need anything from her, if it's in her power, she will grant it. She offers to be a "mother" to you if you will think of her that way, and to teach you about the plants, herbs, and potions she concocts. Because she considers you "family", she doesn't charge you. In Chapter 7, she gives you advice on how to deal with Marc Antony. She says you'd be better asking your favor for Syphax directly because if you fail to manipulate him, he will be set against you. In Chapter 8, she prays with you for a positive outcome for Syphax. In Chapter 16, she provides you with a paralytic for Aquila or if you choose, a love potion that would drive him wild. In Chapter 19, she realizes that one of the poisons she sold was used on Main Character. She tries to give her the antidote, but is stabbed in the process.

Lucanus Flavius
