Despot4Despot: Have my Empire if I Can Have your Cold, Cruel Love!!

Imperia Hali Fortessence aux Val-Regalia, daughter of Kaska and Hwyngarde, third of her name, and ninth empress of the Regalia Universum, the rightful demesne of humanity that rules from the Nebula Orion to the Cygnus Spur, lives a suffocating life on her ivory tower throne until she finally meets Justicia Eowyndel XI, Crown Princess of Helstorm, and her natural predator, eager to prey on the vulnerabilities of her prudish, sheltered and lonely existence.
