(Picture of Sheelal and Kummar) Explanation time! This is my first comic, and I'm not expecting much of it... Of course, I can explain where each character comes from.
-Background! The planet Kalee is an outer-rim war planet. Before the Clone Wars, it was invaded by the Yam'rii (giant praying mantises...) Sheelal is the leader of the revolution against them. He named his band of fighters the "Kolkpravis," meaning, "The Elite" in Kaleesh. The comics take place in Sheelal's free-time =3
-Qymaen jai Sheelal later becomes General Grievous. He is their leader, although he is shorter, and probably less capable than the others...His name comes from the Legend of the Dreamer, a Kaleesh story about two young demigods who fight against an invasion. ("Sheelal" means "Dreamer")
-Ronderu lij Kummar is the close partner and second-in-command to Sheelal. She is supposedly the demigoddess who fights alongside the Dreamer in the story. (Sheelal kinda has a thing for her...) She has mysterious origins, and a fiery temper.
-Bentilais san Sk'ar (or Sans) for the purpose of this story, is Sheelal's bodyguard. He was apparently brought in against his will, as is seen through his hostility towards Sheelal and Kummar. These usually only end in violent pranks. (Sk'ar is better known as an Imperial General in some Marvel comics, but according to Wookiepedia, was a part of the Kolkpravis band.)
