"The Assassins Brotherhood is a recently formed, unaffiliated, secretive organization of highly talented assassins.
They have a near-perfect track record of committing highly visible, extra-judicial killings, with no direct collateral damage and escaping unidentified afterwards. Their location is a complete mystery, and all attempts to hunt them down have ended in failure.
Their philosophy or "creed" instructs their organization to protect the weak by targeting leaders of authoritarian states."
