Argulor was an aging male golden eagle who initially lived in Mossflower Woods, but would move out to a mountain home in the West for a season, before returning back to Mossflower for the next season/s.
Because of his age, his sight was very poor and he was slow moving; he is described as having curving talons and a fierce hooked beak. Generally, he dined on the clumsy vermin troops from Kotir. In his long life, he had a healthy relationship with Verdauga Greeneyes, both respecting each other's power. However Verdauga's daughter Tsarmina was afraid of Argulor, and insisted on his death by the throwing of spears and stones and the shooting of arrows at the bird. Tsarmina herself constantly tried shooting the golden eagle whenever she saw him, but he was always out of range of her bow.
Having never tasted pine marten, Argulor's primary goal was to eat Ashleg, who was under the service of the Greeneyes family. Argulor was fooled when he attacked Bane, who was wearing Ashleg's former cloak.
Stricken with disappointment and injured from Bane's waving sword, Argulor's ancient heart gave out and he died mid-air, falling from the sky with Bane still held in a deathgrip.
- The Bane-Argulor killing is the first of several Mutual Kills in the Redwall series.
