The Everblack Cult

Summary
The Everblack cult is a group of people skilled in the arts of shadowmancy. Using their honed power, the Everblack Cult has become a well known group of assassins that are hired to carry out various contracts. They will only accept contracts if the pay is good enough, and will only accept members into their family if they prove that they are worthy enough. This often results in a demonstration of skill in some manner. Either by killing a truly difficult target, or by displaying a certain mastery over shadow magic.
