Abrogail Thrune was born in Westcrown, then the capital of Cheliax, in 4598 AR.
The Treaty of Egorian was signed on the 19th day of Calistril, 4640 AR, and marked the commencement of the rule of House Thrune over Cheliax and its territories. Using bound devils, the forces and allies of House Thrune were able to subdue all other claimants to the throne, and restore a much sought-after peace to the country. Her early reign was marked by the relocation of that nation's capital from its traditional place in the port city of Westcrown, to the inland city of Egorian on the shores of Lake Sorrow. The powers of Hell sent a pit fiend named General Gorthoklek to act as a teacher and adviser. The devil cloaks himself in a human guise when at court, but his aura of evil is undeniable.
Having served her house faithfully during the civil war, the Queen asked Lictor Jaisade of the Hellknight Order of the Scourge to relocate to Egorian to serve as her personal guard and police force. Jaisade declined, stating that although the Order will continue serving the empire and promoting its version of the law, it will not submit to outside rule and compromise its ethics.
Queen Abrogail was succeeded by her son Antonious, who killed her to take the throne in 4672 AR. She was the great-grandmother of the current ruler of Cheliax, Abrogail Thrune II.
