Enyo Typhos is Siobhan's clone. She was created out without Sio's knowledge by a cabal of genocidal HRDs who wanted to go all Skynet on the galaxy. She was meant to be a living weapon, taught to hate her template and progressively cyborgised. Eventually rebelled and toppled her makers and free her siblings...though some of their views rubbed off on her, turning her into a very amoral person. Siobhan knows of her, though they've never met. Enyo has moved on from hating her since her makers told her lies about her template, but sorta looks down on her. Besides, morally they're quite opposed. They'd definitely fight if they met. Runs Archangel.
Kyriaki is Elpsis'. In contrast to Enyo and Sio, they will actually get on when they finally meet. Presently she's stuck on a Dark Age planet where Elpsis was originally captured and brainwashed by tyrannical Jedi Lords. Elpsis was able to overcome her captors, but a splinter group used her DNA to create a more obedient clone. Kyriaki fell into the hands of a very nasty Sith cult when they stormed the lab. The cloning process was flawed and she was woken up prematurely, which manifested in various ailments. So Kyriaki has been raised in a nest of vipers, forcing her to become cunning and ruthless, though she still tries to hold on to vestiges of conscience and mitigate evil. Admires her template, though she knows little of her. She'll be the brain to Elpsis' brawn.
