Rigel is the male squirrel King of the Kitalpha squirrels. He is the mate of Kuma and Arietis, and the father of Hollyfire in Hollyfire53's fan-fiction story, Hollyfire's Tale. He was a friend of Schedar's, and a very popular King.
Later, after Arietis had joined their band, Rigel made the decision to go to Salamandastron. He then met Digclaw, who guided them to Skipper of Redwall Abbey, and indirectly got Arietis killed. Later, at Redwall, Rigel made friends with Skipper, then abruptly left after Arietis's death.
He made friends with Reedwater Carlson, and had the dream that told Skipper to make Hollyfire a Warrior. Rigel, Reedwater and Hollyfire are known to be the only of the group to survive the trip to Salamandastron.
Rigel was also the first squirrel to make friends in Holt Lightflames.
