The ancient Zemurian civilisation (古代ゼムリア文明) refers to the inhabitants of Zemuria prior to the Great Collapse. The civilisation was destroyed during the Great Collapse, leaving behind advanced technologies, such as orbments, and ruins throughout the continent.
In practice, every remnant from before the Great Collapse is referred to as 'ancient'.
The ancient Zemurian civilisation was divided into at least seven major factions, each centred around a Sept-Terrion.
- Aureole centred faction, led by Celeste D. Auslese, on the Liber Ark (Liberl).
- Demiourgos centred faction, led by the Crois Family, in what is now known as Crossbell.
- Ark Rouge centred faction, now known as the Hexen Clan, in the land of Erebos (Erebonia).
- Lost Zem centred faction, now known as the Gnomes, in the land of Erebos (Erebonia).
