Star Wars Headcanons

Amayian is a sith, as he able to use Force Lightning, yet allows his emotions to be submissive to him, gaining himself power, while not allowing himself fall victim to its control. Through this, he’s cold, calculating, and ruthless. But he does not follow the path of the Jedi Order, and finds them limited in their own view of the world. His anger is silent, his wroth hidden behind detachment.
Alexandra is considered a normal Sith - she revels in her power that is obtained by anger, yet uses her powers to also help those around her, especially the downtrodden. She rises quickly to become a Dark Lord of the Sith and than later Darth. But she is not unafraid of using those around her as well, and to gain personal power too.
