Ghost

Ghost is a character that NovelAI introduced during "Twitch Chat and I invaded Space with Artificial Intelligence". Ghost was originally an assassin sent by the humans of Earth to defeat the emperor of the Chatern Empire, but Ghost instead became the Chatern Emperor/Empress and ruled the empire for the rest of the game.

The AI writes Ghost with inconsistent gender, referring to Ghost as "he", "she" and "they" at different times, and as an "Emperor" or "Empress." So Ghost is speculated to be genderfluid or similar to it, though it is not confirmed what Ghost's gender identity is.

Even though Ghost is the emperor and empresses, Ghost is somehow also the emperor's wife. Ghost also impregnated the Empress - herself - and gave birth to twins, Arbiter Junior (who is normal) and Arbiter Senior (who is a clone).

Origins
Ghost was originally an assassin sent by the humans of Earth to kill the Chaturn Emperor, because they were pissed that the Chaturn Empire's Death Star exploding during construction and killing everyone on Mercury. But Ghost failed to kill the Chaturn Emperor, and instead took his place.

As the Empress of the Chaturn Empire
Ghost is a master of martial arts, and he used these skills to become a powerful empress. He quickly conquered the Empire of Chaturn, but during his reign he suffered from sever delusions of grandeur and invented the evil anti-matter bomb.

The humans of Earth were pissed, and decided to build a giant robot called Arbiter, a genetically-enhanced human soldier who has been trained to fight aliens, and they send the Arbiter to defeat the new Chaturn Emperor. Arbiter defeats the new Chaturn Emperor, but then he comes face to face with Ghost, who had became the Emperor's new wife (making Ghost their own wife). Arbiter falls into a deep depression and thought that all of his efforts had been in vain.

After Ghost impregnated the Empress (herself ), she gave birth to twins. One twin was normal and one twin was a clone. The normal twin is named Arbiter Junior and the clone is named Arbiter Senior. The humans of Earth sent the Arbiter Twins to destroy the new Chaturn Empire, and succeeded in destroying its new Death Star.

Meeting with Jar Jar
Empress Ghost looked towards recruiting a new ambassador for Chaturn Empire. The empire had heard that Jar Jar Binks, the weird fish-man and then-former ambassador for the Dougtopian Empire, had recently been chased out of Dougtopia and had barely escaped with his life. So Ghost headed out with their space fleet in hopes of finding and probing Jar Jar Binks and recruiting him into the Chaturn Empire.

Ghost arrived at the planet Zeltros, and they saw Jar Jar standing upon a cliff above large city that was burning. Jar Jar apparently already knew Ghost, and greeted them. Jar Jar decided that before talking about being recruited into the Chaturn Empire, he would tell the long story of how he got there. The story seems to impress Ghost, but they get straight back to the point and ask Jar Jar "Anyways, wanna join my Empire?", to which Jar Jar replies "No thanks," as he was happy where he already was.

Construction of Sun Tzu
Unfortunately for the Chaturn Empire, Jar Jar Binks left to rejoin the Dougtopian Empire on Mercury. Empress Ghost realizes that there are much more important things to be handling, and Ghost tells the top Chaturn scientists to being building a new Sun, which would become Sun Tzu. Ghosts commands that the new Sun be be beautiful, powerful, and loving, but the Chaturn scientists disagree. The scientists think that they know what the Emperor Ghost wants better than he does, and so decide to build a Sun that is ugly, weak, and mean.
