The Touraine are one of the more complicated families in Komaru, and thrive on opportunities that most other families would ignore. Their lands are along the western coast of Komaru, and they show a surprising level of comfort in the presence of the ocean's wrath. Most other nobles think of the Touraine as the opposite of butterflies: Touraine children seem to be born showy and energetic, but at some point in their lives they all seem to transform into stuffy and mysterious white-haired elders.

Much of the Touraine mystery comes from the difference in the family's public and private expectations. Traditional Touraine sensibilities demand an impeccable appearance of propriety while encouraging the opposite sort of behavior outside the public eye. Touraine public morals strongly resemble those of Victorian England. Emotional restraint, obedience to the rules of etiquette, and careful attention to distinctions of rank are all virtues among the Touraine, at least among other nobles. As such, Touraine men are expected to go forth into the world at a young age and behave with dignity, panache, and honor. Women, in comparison, are encouraged to seclude themselves in their studies and to act with taste, restraint, and prudence.

Privately, the family demands a very different set of rules of conduct, and those who dare to break the rules are generally accorded the most esteem. The perfect Touraine noble keeps his or her reputation above reproach while secretly breaking every rule of polite society. This paradox is why most Touraine profess to study the occult. By engaging in something forbidden and escaping the consequences, a Touraine gains status with his peers. In comparison to the status boost, any power or advantage gained is secondary in importance.

Most hot-blooded young Touraine either fail to live up to this expectation or actively flout it. When youthful Touraine fail to hide their improper activities, their elders are quick to punish them for their offenses. In these cases, the youth's actions themselves are not frowned upon as much as the lack of care in concealing them. Eventually, most Touraine youths either learn to hide their indiscretions, or are locked away by the family's elders where their mistakes cannot be seen.

The Touraine family is highly idiosyncratic in its naming conventions. Traditionally, female Touraine are named after virtues, while male Touraine are named after precious or semi-precious stones. House Touraine's colors are blue, white, and green.
