Riggu Felis

Riggu Felis is a wildcat warlord who rules on Green Isle and lives in a huge wooden fortress. He has a wife, Lady Kaltag, and two sons, Jeefra and Pitru He is supported by an army of wildcats, who keep the native otters of the area as slaves.

Once, in a battle with the great hawk Pandion, Riggu was defeated by him and the hawk's talons teared at half of his face. After this major injury, Riggu was forced to wear a half-mask made of chainmail, disguising his wound. Though he managed to stick a star-shaped iron barb into Pandion's mouth, Riggu does not easily forget what the hawk did to him that day, and has his eye on revenge.

Returing to the fortress, Riggu encounters trouble several times with Leatho Shellhound, a rebellious otter who leads his fellow otters in several battles. In one, his son Jeefra appears to drown, but in reality he has been killed by his brother Pitru. Through a series of strategic battles, Riggu eventually gains the upper hand and captures Leatho. He is thrown into a cage in the fortress.

Eventually he escapes with the help of Pandion, but soon after his new hiding place is set ablaze by Lady Kaltag, driven mad at the death of her son. Pandion and Brantalis, another bird, are sent to rescue him by Tiria Widlough, who has come to Green Isle to liberate her people and fulfill the prophecy of the High Rhulain. They carry Leatho down, but Riggu, fighting a battle with the otters below, recognizes Pandion, and throws his axe at him. Pandion falls to the ground, dead. Then, Tiria, who has sworn to pay back the man who put the iron barb in Pandion's mouth with his own weapon, loads the iron star onto her sling and fires it straight at Riggu. It hits him dead-center in the head, and he dies. Soon after that, justice is restored to Green Isle, and the otters are allowed to live in peace.
