2 and 9: There are other communities of vermin besides the Juska. In Outcast of Redwall, there was the tribe of foxes led by Shang Damsontongue that lived in the gorge. The water rats in Marlfox were indigenous to the island. The river rats in Legend of Luke and Rakkety Tam have their own colony by the rivers. Also, the Northern Mountains have not been fully explored. The closest was Thrugg and Dumble in Salamandastron and Deyna and his pursuers in 'Taggerung''.

Many vermin groups are said to come from the north, so it could be the deep northern mountain range.
