The Battle of the Twin Realms - Final Fantasy XVI Database

In-game Description

The Battle of the Twin Realms was a conflict fought between the Holy Empire of Sanbreque and the Kingdom of Waloed in the year 865. Sanbrequois forces, with the power of the Eikon Bahamut on their side, took the Strait of Autha back from Waloed, putting an end to a blockade that had lasted several decades. The Waloeders, looking to hold back the Sanbrequois advance by any means necessary, formed an alliance with the Dhalmekian Republic—who themselves were waging war against the Iron Kingdom on the western front—and prevented the empire from progressing any further.
