Cassius Alistair Magnus is the reigning Emperor of the Old Empire with the reputation of being cold and merciless. He has ruled since the age of twenty one, and has made an impact on the Empire due to his ruling style.
He has brought some stabilization by ceasing expansion efforts, however he has not managed to quell the chaos on the Empire's borders, or eliminate the unrest outside of the heartland. Still, any open rebellions or moves against his throne have been mercilessly crushed by his legions, leading to less occurrences during his reign.
He has three children. Alistair Magnus, his oldest son, whom he has retracted the crown from currently. Though he would not admit it, he has only done so in order to teach Alistair a lesson and wants him to earn it back. He treats Alistair cruelly in order to toughen him up, because he believes that a weak Emperor will devastate the Empire in it's current state.
He also has fraternal twins (male and female twins): Lional Magnus and Lilith Magus. He has a better relationship with the twins but still keeps them at a distance, especially Lional. He is preparing Lional for the possibly of taking the throne, in case his eldest son is unable to live up to his standards.
Rules with an iron fist, rarely if ever shows mercy
