Calvin was a nipsie who lived at the Seven Kingdoms of the Nipsies at the Fablehaven preserve. He was enlarged by a spell, making him their champion and a giant amongst his own kind, though he stood only around eight centimeters tall. By being elected as the nipsie champion, Calvin's mission was to break the curse cast on his people by the demon Graulas. After seeking out Seth Sorenson, slayer of Graulas, the two banded together, with Calvin pledging his loyalty to Seth, and Seth promising to help with the curse.
Calvin goes to Seth Sorenson, initially appearing a mouse until Seth drinks the milk to see Calvin's true form, and Calvin explains that Seth, as the slayer of Graulas, is a part of a nipsie prophecy to undo a magic curse that was cast upon the nipsies long ago, making them less than what they originally were.
Calvin was selected by the leaders of his people to serve Seth and was magically empowered to make him more able for the job. Seth accepts Calvin's service but asks him to be his friend rather than his servant. Another reason Calvin wishes to go adventuring is to find his beloved, Serena, another nipsie who left Fablehaven long ago to learn of the curse on the nipsies.
Calvin accompanies Seth and his sister Kendra to Wyrmroost after the siblings have accepted Agad's request to become the new caretakers of the sanctuary, and Seth introduces Calvin to his sister, grandparents, and Marat, who suggests Calvin could be a useful spy as long as the staff of Blackwell Keep doesn't become aware of him.
As champion of the nipsies, Calvin, despite only being roughly eight centimeters tall, he stood around six times as tall as regular nipsies. Proportioned like a normal human, he had black hair, blue eyes, and spoke in a squeaky voice. Calvin owned a dark yellow short which he tucked into a pair of brown pants. He was also seen wearing travel-worn boots and a sword. To an individual with their eyes closed to magic, Calvin appeared as a mouse.
