Greater Dominion Calendar

The Calendar of the Vil-Nolwikkan Greater Dominion, usually shortened to "Greater Dominion Calendar," is the year set after the destruction of Sonen. As Sonen had its own calendar, Archlord Delodosius I declared the year that Sonen fell as "Year 0 of the Greater Dominion." The calendar has stuck.

For example, Sonenese Emperor Ourias Di Soneni vanished in the year 12,363 BGD, while current Archlord Reskullus was crowned in the year 1290 GD.
