Antiquity
From Chrono Wiki, a database for the Chrono series that anyone can edit
The Antiquity (also known as Dark Ages in the SNES/PS version) is the year 12000 BC in Chrono Trigger. This is the year where Lavos destroyed all of Zeal and made the people of Earth forget how to use magic. Queen Zeal, Schala, and Magus are from this time period.
