Lethe

Lethe is a fierce, dutiful Cat Laguz from Gallia in Fire Emblem: Path of Radiance and Radiant Dawn, known for her initial hatred of humans (beorc) but develops trust with the Greil Mercenaries, especially after Ike protects her, leading her to fight alongside them against Ashnard and later serving as a respected Gallian commander. She is the protective older twin sister of Lyre, often stern with her but fiercely protective, despite their frequent arguments.
