Mordred

Emperor Mordred IV, also known as Mordred the Arthur, the Usurper or simply Mordred, was the emperor of the Arthurian Empire after a successful coup against his sister. He was a skilled manipulator and used his charm and ownership of slave brothels and fighting rings in nearly every city in the Arthurian Empire to both accrue intelligence on political rivals and acquire vast wealth that almost outmatches the royal treasury.

Despite his charm, he was widely considered to be the worst commander in history, believing that it is only through the size of their military that would grant him his victory. where he is ultimately responsible for the downfall of the Empire through the suicidal and futile war against the technologically superior German Empire.

Background
Mordred was the first son but second child of Emperor Lancelot and Empress Elaine. As the line of succession was absolute cognatic, he was second in line to become Emperor, which was said to have infuriated him. Mordred was raised in the Dragon Keep of Camelot, where he was raised to understand etiquette, which was a ploy by his father to be his sister's advisor, which made him even more infuriated at his parents, vowing to return the Arthurian Empire back to an agnatic succession.

During his father's reign, he later used his influence to gain many powerful allies in the council and started planning to depose his sister and take the throne for himself, stating that it should be a "true son of Arthur" to lead the people of the Arthurian Empire. The coup started when his father died in his sleep, where he seized control of the throne and forced his sister to flee into exile, starting the Arthurian Civil War. After the western portion of the Arthurian Empire declared support for the return of Empress Guinevere, Mordred's first act was to establish the Imperial Army, which would completely remove the social structure of feudalism, which proved very effective in gathering troops and forcing the loyalists into what seemed like a quick victory.

Recent History
However, an army of Germans arrived from beyond the Gate, which destroyed every army sent forth to them by Mordred. The Usurper insisted on continuing their fight, pleading to the council member's honor and their proud history of defeating any enemy put forth to them. Realizing that the Germans would side with Guinevere against him, he sent an army of 300,000, led by Mordred himself, to destroy the last of his sister's army at her own capital of the city of Guinevere. Unexpectedly, the army was crushed when an army of thousands, led by Werner von Goldberg, destroyed the army at the Battle of Guinevere, terrifying him into retreating back to Camelot.

Trivia

 * He is mostly based on Zorzal El Ceasar from Gate cannon series due to their share of incompetency and idiocy in leading armies and the belief that vast number of troops can win anything, not strategy or tactics.
