Revolution
The people of the Ranginian Empire, lead by prince Adriel Bellum rose up against the tyranny of Vortigern Caelum.
The prior emperor, Vortigern Caelum, was dethroned by his own son. His reign had become tyrannical and people suffered from his ruling. The prince, who felt ashamed by his father's actions, tried to put a stop to his madness. However, he did not listen and a conflict ensued.
The civil war was won by the rebels and the emperor was killed in the conflict after it was discovered that he allied with demons.
