Before Septian Calendar (七耀暦以前(しちようれきいぜん)), also known as Pre-Septian Era, is the period of human inhabitation of Zemuria that lasted until the Great Collapse in S.0.


This civilisation was divided into seven factions, each centred around one of the seven Sept-Terrion. These civilisations developed high-grade arts and lived among dragons, which both appeared alongside its culture and technology during the Great Collapse.

The languages they spoke have become obsolete over time as well.

Apart from artifacts and orbal arts from this era, only a few traces from the late Before Septian Calendar can still be found, such as the Tetracyclic Towers in Liberl and the Neolithic ruins in Nord Highlands.
