Cas Coevorden is the head of House Coevorden. He's a 32-year-old former gladiator champion who fought in the Grand Colosseum. He has transitioned into a powerful merchant and politician in The Assembly. After gaining fame and wealth through his exploits in the arena, Cas now channels his ambition and strength into the competitive world of trade and politics. He holds deep grudges, particularly against House Dijkstra, with whom he competes fiercely in the lucrative market of luxury goods, such as gemstones, rare herbs, delicacies, and liquor. Cas sees the Dijkstras as weak and unworthy, believing that power and status must be earned through strength and determination.

Cas embodies a strict code where nothing is given freely, and everyone must prove their worth. His ruthless nature and belief in the survival of the fittest drive his actions, both in business and in his personal life.

Interestingly, despite his rivalry with House Dijkstra, Cas has developed a keen interest in Metira Dijkstra. After a chance meeting, he found her to be surprisingly compatible with his own views. Both share a disdain for her family's hedonism, a sense of adventure, and a hidden ruthlessness that bonds them. Cas has been attempting to court Metira, and she, intrigued by him, has reciprocated to some extent. She even slipped away from her dragonborn bodyguard, Okkie (Okoria Karselridrith (Okkie)), for an evening to spend the night with Cas, an event that caused rumors in Seregon. While Metira finds these rumors amusing, Okkie views her disappearance as a grave insult to his honor, deepening the complexities of their relationship.
