Onu

Yanu's Little helpers

The Onu served as Yanu's secondary attendants, handling smaller yet crucial tasks that did not warrant the direct attention of the Ynue or Yanu themselves. They existed in diverse forms with various functions, but alas, many of them faced extinction during the Ynue rebellion, leaving only a few survivors.
During the early days of Yanu, they had been the labourers, to complement the Ynue's architectural function, they were the ones who did the little things, which together made the big things happen, they may not have been the most powerful, but they were nonetheless important, even if their current position in this world is that of a relic, from history long past.

Due to them being created from part of Yanu's energy, they are incapable of reproduction, this is also why they were sent into extinction so easily.
