Indigo Vantases and Blue Pyropes.
The Grand Absolutionary is one of the foremost voices of the Alternian Empire, said to have been hand-picked by His Ascended Highness to represent His message of enlightenment and lead trollkind away from their inherently violent roots.
Karkat Vantas is one of the few pre-ascension trolls to have visited the fleet, and to have met his ancestor in person. He is currently being groomed to become his successor, as the Absolutionary is getting old and the Empire can’t be without its voice of forgiveness for long. It’s a lot of pressure.
The Carnifex was the single greatest fighter Alternia had ever seen. Traitors, criminals, and other irredeemable degenerates were thrown into a ring with her and they didn’t come back out, except for one. When faced with the task of executing an oliveblood who served as one of the Signless’s lieutenants, the Carnifex threw down her cape and resigned.
Terezi Pyrope, despite being entirely self-taught, is a master of martial arts and misdirection, which she mostly puts to use while FLARPing with her friends. Her vision is severely limited thanks to an accident during one of these games, but that doesn’t seem to have slowed her down any.
