Mhera was a female otter Abbess of Redwall Abbey. She was the daughter of Rillflag and Filorn, elder sister to Deyna, and a descendant of Deyna I. During the time when Deyna was being cast out of the Juskarath, Lady Cregga Rose Eyes had decided that Mhera should be the next Abbess of Redwall Abbey. She then put into motion a plan that she and Abbess Songbreeze had conceived many seasons ago.
