Who is Rubra from The Neutronium Alchemist Conflict and what is their importance?

Rubra is the habitat personality and controller of Valisk. He was once a living person, who broke away from Edenist society because he was unable to believe in and accept its precepts and beliefs. These rebel Edenists are sometimes known as 'serpents.' Rubra went onto grow his own independent habitat, Valisk, to house his new company, Magellanic Itg. Over time, he became very rich and successful. After his death, Rubra transferred his memories and personality into the neural strata of Valisk, becoming the habitat personality. Rubra is described as a strong, controlling personality, who likes to feel that he in power over every situation.
