They appear again in the end of volume 8 and in volume 9. It's explained that they cannot use magic, but the developed a way to mimic it by using elementals as fuel, which explains Avant Heim hatred for them. It's also stated that their lifespam is about 6 thousand years.

By the time Sora and Shiro come to Disboard, only 13 remain, but they cannot reproduce due a lock of the heart, that will only allow "the one" to reproduce with them. In volume 9, they think Sora is the one, and so he spend the whole volume avoiding their "sexual attacks" and trying to prove he isn't.

Einithi is the only male one left, the other 12 are females. After the Great War, Einithi developed a strong peronsality and doesn't speak like a machine anymore.
