There’s this one channel I watch called UsefulCharts. He does videos on genealogy and studies Royal lines and stuff. Why do you think I’ve been trying to find when the old kings of Ravenna died, or how long ago Ravenna was established?
Here are my findings based on quests and NPC dialogue.
Gallio Bronze during the Mines Arc: he said something about Akursius Keep being a Bronze Legion fortress for around 20 years
Rackham’s Journal: Akursius Keep fell in January Y1807
Quests Tab: The Nimbus Sea Arc starts on December 6, Y1854
