Aita

"It was Aita who volunteered to see if it might be done. Aita, my husband, my love."

- Juno.

Aita was a member of the First Civilization and the husband of Juno.

First Civilization
In his time, Aita helped Juno, Minerva, and Jupiter sort through the solutions given to them at the Grand Temple, in order to prevent the First Disaster, which he was able to do until the fourth solution was tested.

After their first three attempts of preventing the First Disaster failed, Juno and the others sought to save their race by means of smaller proportions. The fourth solution was to internally change the bodies of their kind, to what would survive the new, hostile world to come. In order to test this solution, they would need a living test subject, for which Aita volunteered.

As the solution was tested, Aita's mind deteriorated within an instant; while his body would survive, his mind became brittle and catatonic. With enough will, he asked his wife to end his suffering, and Juno regrettably fulfilled his request by stabbing him in the heart, euthanizing him.

Legacy
Despite his death, the experimentations of Juno had some success. Throughout the next millennia, Aita reincarnated in the bodies of some of his human descendants such as Bartholomew Roberts and John, giving them his appearance and some of his memories.
