Vigil

The Vigil is a worldwide Daemonstri organization whose purpose is to defend and protect the races from inside and outside threats. Members are known as keepers. The Vigil has a number of divisions based on location (Europe, North America, Asia, etc.), and each division has a High Keeper, who is a member of the Council of High Keepers. All keepers are Nefili.
 * The Vigil's motto is vigilia perpetua, which is Latin. The translation in English is literally "eternal watch," but the phrase "the vigil never ends" is used as a translation in the books.
 * The Vigil's insignia features an owl.
