Saxons

The Saxons is an ancient crime syndicate of supernatural humans and Norse demigods. The Saxons frequently act as mercenaries for other evil powers: including the Jotuns, Fomorians, Apotheosis Initiative, or even just human mafia groups. Sometimes during these jobs, the Saxons come into conflict with demigods and heroes from different mythologies.

For the past fifteen centuries the Saxons have been in conflict with Camelot but neither side has ever been able to destroy the other.

Description
The Saxons are divided into thirty-five semi-autonomous chapters each with it's own leader and under the command of the Elder Council. The decentralized nature of this organization makes it hard to crush them completely but it also means the Saxons won't be taking over the world anytime soon.
