Feh takes residence in the player's Castle on a special perch. Normally, Feh is asleep, but will awaken whenever the player receives an in-game gift.
Feh also runs a special YouTube series called Feh Channel, where she helps to announce upcoming events in Heroes.
- During the Fire Emblem: Lost Heroes event in Dragalia Lost, Feh made a cameo on the event-exclusive wyrmprint "The Order's Messenger Owl".
- This makes her one of two Fire Emblem characters to appear in the event, but not be playable, the other being Loki. Unlike Loki, however, Feh did not play any role in the story.
