Rubicon's and Oumou's fanchild Lunive Rubicon
Actually ze was an accidental child.
Rubicon and Oumou didn't know they had similar genitalia, but that wasn't a problem for them. Rubicon felt very lucky because he would have a highly intelligent and incredible mixed-race child
Lunive is just like zir mother... Genderless, but because zi looks like a woman, this isn't very noticeable.
Lunive worked for both the Builder and the TTA. Like zir mother, the Builder was't a "context." role Although she could be in the "build" role, it suited zir perfectly, and ze usually worked with zir father in the TTA until Rubicon died... Rubicon handed over all his work to Loretta and Lunive, but Lunive didn't want this and wanted to leave the Milky Way galaxy with zir mother, but Oumou wouldn't allow it. Lunive left permanently
Lunive was 13 when ze left, and by the time she returned, ze was already 25, and in certain time paradoxes, ze had spent nearly 100 years (not for the Milky Way galaxy) and returned to the Milky Way galaxy, noticing that everything had changed except for zir mother. Loretta was now in 30s, and science had made great strides for the Milky Way galaxy thanks to Oumou, but she had lost both her husband and her daughter.
Lunive was very afraid to go because ze thought zir mother would be angry with zir and wouldn't want zir but everything turned out the opposite :3
Lunive is the spitting image of her mother, having only inherited zir father's hair and skin genetics.
In fact, after seeing the baby, Loretta said,
"At least it's clear you're his, Professor:3"
Is there really such a thing as ze/zir? I hope you're right, ChatGPT 😭
