An incarnation is a person who embodies in the flesh a deity, spirit or quality. The most known incarnations are those of the 7 sins and 7 virtues, however there are other similar creatures. Typically humanoid, they mainly adhere to the structure of the societies they find themselves in. Their powers are dependent on what they are incarnations of as well as dependent on the deities they are incarnations of, as they have direct control or influence on them. They cannot pass on their incarnation status to their children, as the incarnation status only passes on when the person formerly holding that status has either passed or was "purged". The incarnation is then passed on to a child that is being born at the same time the former is expiring.

(Take a shot everything you read incarnation(s) and you'll be dead by the end of this, lol)
