Constantinus is Phoenicia's last magistros, before it fell into Baltrhein's control.
Considering his station as someone in charge of a country, Constantinus is rather naive and idealistic, earnestly believing in Phoenicia's past glory as the biggest empire in Rumeliana. This leads him to make rash decisions when the said glory is threatened, such as when he declared war on Baltrhein Empire.
