Lethe (レテ Rete) is a playable character from Fire Emblem: Path of Radiance and Fire Emblem: Radiant Dawn. She is a Cat Laguz from the Beast tribe of Gallia. Fierce and agile, Lethe initially bore a deep-rooted hatred for all beorc, but after fighting alongside Ike during The Mad King's War, she has since learned to let go of this hatred, forming several friendships in the process. She is the leader of a small platoon of Gallian soldiers. In Path of Radiance, if Lethe and Ranulf share an A rank in Support Conversations, Ranulf will offer Lethe the opportunity to return to Gallia, leaving Ike and the Crimean Liberation Army behind her. Lethe will then decline this offer, promising to defeat Ashnard alongside the Crimean Army. Lethe has a younger twin sister named Lyre, and despite their arguments, Lethe only desires for Lyre's safety. Lethe will always try to protect Lyre, even if she has to be mean to her. Lethe appears as a boss in the Radiant Dawn chapter, A Reason to Fight, but the player will neither be required to fight nor defeat Lethe in order to advance through this chapter.
