The Sisters of Senescence are known in the public eye for their utterly single-minded mission to fully terminate any who would shirk that universal duty of all living things: to die.
In the eyes of the public the bombast with which these goals are pursued and met is a necessary evil. The majority viewpoint is that while it is very inconvenient to be late to work after a firefight breaks out between Sisters and one or more Escapees on the Kennedy Expressway, better that than to permit Escapees' flagrant violations of Maxwell's Laws of Thermodynamics to collapse all of reality.
However, there are some Sisters who take a more subtle approach than the typical gamut of guns, rockets, tactical nukes, etc. These Sisters operate by subterfuge, in secrecy. The most common mission for these traditionalist assassins involves the selective deletion of Escapees in regimes elsewhere on Earth who do not enforce Maxwellian Entropy strictly, if at all. This is Lady Morgét's field of expertise.
