The Neolithic Civilisation (巨石文明) is a civilisation that inhabited Nord until approximately S.200.
A number of ruins from the Neolithic era can still be found through Nord.
One such ruin is the Ancient Quarry (石切り場), which the Neolithics built and operated during the Dark Ages. Local legends dating back from the Neolithic era suggest that the Guardian sealed away an evil djinn in the quarry.
The Stone Circle, situated in southern Nord, is another ruin from the Neolithic Civilisation. Its exact purpose is unknown, but as a place connected to the Spirit Paths, it may have served as a place to enshrine spirits of animism.
