Significance of Wicken Fen

After Agba breaks the rules at Gog Magog, he and Sham are punished by being sent to the dismal swamp land called Wicken Fen. They live there alone, struggling to survive everyday, although the Earl does have some sympathy for them and sends them food regularly. The time Sham, and Agba spend in Wicken Fen is one of their lowest points in their lives.
