The Mandatum

The Mandatum is a secret society that's dedicated to sending demons back to Hell. Consisting of hunters grouped in seven, they deal with non-humans (demons, mythical creatures, etc).

The official language of The Mandatum is Latin, making every Hunter- at the least -bilingual (their native language and Latin). Because they are a society spread throughout the world, Latin is their universal language and makes it easier for Hunters to communicate.
