The underground society that engages is guerilla warfare throughout the Kingdom of Kel. Heavy hitters that have landed many crippling blows to the likes of the Hand of Ubris and other supplanters of the people of Kel.

It is an organization that is hundreds of years old that many say spring out of the heart of those that are loyal to the kith and kin of Kel.
