Heather is a playable character from Fire Emblem: Radiant Dawn. She is a wandering rogue who scours the countryside villages of Crimea for gold to pay for her sickly mother's medicine. Heather is introduced when she arrives in the village of Ohma during a battle. Around this time, Brom and Nephenee enlist her aid in stopping an insurrection in Ohma. For the duration of Ludveck's rebellion, she assists Lucia and Elincia in their efforts to stop it. After the war concludes, Heather returns to her home to care for her ill mother and swears to put a stop to her thieving ways, although she always seems to have an ample supply of gold. Heather is a cunning young woman who loves to trick men into giving gold and other possessions to her. It is implied that she is the rogue who tricked Gatrie into giving gold to her during the events of Fire Emblem: Path of Radiance, although this is only mentioned in one of the support conversations between him and Shinon.

She flirts with the other female characters, especially Nephenee, and seems to dislike men. In a quote that was removed from the North American and PAL versions of Radiant Dawn, she says that her motive for joining the Crimean Army was to "meet all the pretty girls". She enjoys seeing Elincia, whom she describes as "glorious", and voluntarily assists Lucia, whom she deems an "amazingly stupendously great" girl. She also willingly tricks "some dupe who thinks she's cute" into giving her food, which she later uses to feed Ilyana. She thinks woman are superior than males!
