Baroness Sabine Beck Jr.

Sabine is the leader of the Barony of Beck, the leader of the Populist Faction, a veteran in all the recent wars within the last 30 years. Sabine was supposedly the same Archduchess Sabine Beck that helped found the empire but once records and paintings were check and they revealed that Sabine Beck Sr didn't have horns. This Sabine is still older then most humans reach since she appeared to be in her mid twenties when she reclaimed the Barony for herself and that was about 30 years ago. Her reputation on the battlefield has earned her the title of the Incarnation of War. Sabine is known as a strict and demanding person if you are her subordinate but kind to her friends.
The Becks are barons because of the original Sabine leaving her domain to her descendants to go on a quest and they slowly lost territory from losing their high levels of Mana to maintain their land until they went from an Archduchy to a Barony. Sabine came back and regained control over the Beck Family and turned the remaining member of the Beck Family into a branch family, the Becken Family, after finally becoming a noble several years ago. She came back about 30 years ago but only just was able to claim it because she fought in the wars then was able to attend the Royal Academy to become a noble of Einhorn to be a rightful heir to the Beck title.
