Fey is a commoner boy raised in the same lower city neighborhood as Myne. He is a relative of Lutz and his family, specifically Lutz's cousin. Sharing Tuuli's birth season makes Fey the same age as her.

He has red-tinged hair and purple eyes. His personality blends mischievous tendencies with a fundamentally good heart. Fey is often seen with his brother Ralph and cousin Lutz, especially during activities like gathering firewood near Ehrenfest.

A significant incident occurs when Fey, Ralph, and other boys discover Myne's newly crafted clay tablets in the forest. Unaware of their importance, they jump on the tablets, destroying them. This provokes an intense reaction from Myne; her eyes change color and the boys struggle to breathe under the pressure of her anger. The event leaves Fey deeply afraid of Myne, causing him to actively avoid her afterward. As an apology, Fey and the others help recreate the damaged tablets.

Fey's fear of Myne defines their relationship. He frequently seeks information about her from Lutz, reflecting his lingering anxiety and curiosity. His role is primarily confined to early interactions within the commoner district and does not develop further in later story arcs involving noble society or temple affairs. After the clay tablet incident and its immediate aftermath, Fey's involvement in the broader storyline diminishes.
