Description
Karstedt commands Ehrenfest's Knight's Order. Born the son of Bonifatius, an archduke candidate, he and his brothers trained as archduke candidates due to the ruling family's lack of male heirs. This positioned him in direct competition with Lady Georgine for succession until Sylvester's birth. Reduced to archnoble status before completing his third year at the Royal Academy, he married three times.

His first marriage was a political union with Elvira, an archnoble and sister to the Leisegang-aligned Giebe Haldenzel, producing three sons: Eckhart, Lamprecht, and Cornelius. His second marriage to Trudeliede, an archnoble from the Veronica faction, yielded a son named Nikolaus. His third marriage was to Rozemary, a mednoble with abundant mana whom he loved deeply. Household conflicts erupted when Trudeliede turned against Rozemary and Elvira sided with Trudeliede to maintain balance. Rozemary's death from harassment and stress severely strained family relations.

A stocky older man with reddish-brown hair, Karstedt moves with precision honed through years of training. He exhibits a reliable, honorable personality, taking responsibility for his actions and those under his command. He treated Myne kindly upon her planned adoption, showing familial affection early.

As Knight Commander, he oversees security and guard assignments. During a trombe extermination, his subordinates failed to protect Myne, resulting in her injuries. He accepted reduced pay and covered half the cost of Myne's new ceremonial clothes as punishment. Later, at Ferdinand's request, he agreed to adopt Myne, becoming her noble baptismal father. He investigated corruption in the temple alongside Ferdinand and participated in Spring Prayer travels. There, he demonstrated skilled sword dancing and defended the group against attackers, launching powerful magical strikes.

When Myne transitioned to Rozemyne, Karstedt formally recognized her as his daughter with Rozemary, with Elvira serving as her noble mother. He welcomed her into the family and maintained concern for her well-being, often seeking reports on her activities. His relationship with Ferdinand is one of deep trust; they collaborate on critical matters, including preemptive strikes against threats like the Lord of Winter. He respects Ferdinand despite political pressures and continues treating him as a higher-ranking noble even after Ferdinand's move to the temple.

Magically, his highbeast takes a griffon form. His mana capacity ranks high among archnobles due to his archduke candidate origins. He learned Rozemyne's Water Gun spell but uses it less effectively due to lower mana reserves. In combat, he is one of Ehrenfest's strongest knights.

Non-magical skills include proficiency with the flute and harspiel, along with elegant sword dancing. He maintains neutrality in political factions, prioritizing Ehrenfest's stability, though his marriages created factional tensions. He is grandfather to Siegrecht through his son Cornelius.
