Manamorians

The Manamorians, or Manamores, were an extremely old race thought to predate even ancient humans by millenia. For this reason, while the term "ancient" mostly refers to people from the Age of the Sun and the Grey Era (roughly 2800BD - 0BD), and the "prehistoric" refers to humans before that period, the term "archaic" in a strict historical sense refers to races that predate humans entirely. This is why the archaic wonders of the world are usually called Archaios. All that is known about the Manamorians comes from the little that is known about the Archaios ruins themselves, and the snippets of information given by deities such as Nikina.

Description

It can be deduced that the Manamorians at least resembled humans. Archaios artifacts are all around the right size and shape to be utilised by modern humans, and structural features like windows and doorways are also of similar sizes to be perfectly usable.
