Historical Events
Battle of the Bloody August:
This is where the battle against the beast created when Azalie failed to use the Sword of Baldanders took place. Childman's (Azalie in Childman's body) unit from the Tower of Fang spearheaded the chase, with ended in the death of most of the unit and the destruction of the creature (at the time, Childman).
It's worth noting that during the course of this battle that a significant square was carved into the landscape, making room for a battle arena tens of meters deep. This is where Childman took his final stand against the pursuing Tower sorcerers.
