Lethe

Lethe 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, the leader of a small platoon of Gallian soldiers, and the older twin sister of Lyre. Fierce and agile, Lethe is known as one of the harshest characters in the Tellius series, with her honor and respect for her duty leading her to be extremely intimidating, strictly adhering to her role as a beast-tribe warrior and commander, often being strict on herself and others. Despite this, Lethe does care for her comrades, as can be observed from the contents of her death quote.

Though she serves Caineghis and Ranulf, Lethe does not share their belief of pursuing a policy of peaceful coexistence with the Beorc. Her fundamental disgust with human existence shows when she was tasked with leading Ike to Castle Gallia. She has had trouble trusting Beorc having studied the history of the Beorc and Laguz –where "humans" had exploited and enslaved the "sub-humans." When Soren provoked her, the already tense emotions she felt toward them rapidly escalated. However, after witnessing Ike use himself as a shield to help dissolve the situation, she began to change her outlook having seen that not all Beorc are bad.

Lethe's strong attitude can occasionally invite misunderstandings, and was the reason behind her and her sister Lyre not speaking to each other for a long time. It was not until they reunited in the Laguz Alliance where they reconciled. Despite those arguments, Lethe only desires for Lyre's safety, and will always try to protect Lyre, even if she has to be mean to her.
