Description
Cyrus Rivermoore is an upperclassman at Kimberly Magic Academy, the central setting of the series. He is recognized as a necromancer of considerable power, a mage who commands the bones of the dead, and is regarded as being equally dangerous as the formidable Ophelia Salvadori. Physically, he is an adult male with black eyes and black hair worn at ear-length, often appearing with a beard and a coat.

His personality is defined by a deep and unsettling dedication to his magical research. As a necromancer, his motivations are primarily academic and experimental, driving him to pursue his craft without concern for conventional ethics or the well-being of others. This is most clearly demonstrated when he enters the seventh-year preliminary rounds of the school's combat leagues not for glory or rank, but specifically to get close to the powerful mage Alvin Godfrey. His goal is to steal Godfreys sternum for a necromantic experiment. This act reveals a calculating and dangerous nature, willing to target and permanently depower a fellow student to advance his own studies. His actions throw the political and competitive landscape of the academy into chaos, as his theft directly provokes the Watch to intervene and recover the stolen bone before the finals.

Cyrus's role in the story is that of an antagonistic catalyst. He is not a main protagonist but a significant upperclassman whose powerful and amoral actions create major conflict and shifts in the power dynamics at Kimberly. His key relationship is with his target, Alvin Godfrey. By stealing Godfreys sternum, Rivermoore directly causes his rival to be brought down to normal, stripping him of his usual facility with fire magic and forcing him to adopt entirely new combat techniques. This act defines their relationship as one of dangerous predator to a specific, targeted victim, turning Godfreys personal struggle into a major plot point.

Little is documented about his development across the series, but his notoriety is established through his singular, disruptive actions. His notable abilities center on necromancy, specifically the control and manipulation of bones. His power is such that he is considered a major threat within the academy. His most infamous feat is not a traditional spell but a precise and gruesome application of his craft: the ability to surgically remove a specific bone from a living, powerful mage to use in his experiments, an act that demonstrates both his immense skill and his utter ruthlessness.
