Cluny the Scourge - part I

Summary
Matthias walks down Great Hall when he stumbles and trips in front of the Tapestry of Martin the Warrior. Clumsily picking up the nuts he spilled, he reflects on the attitude of Martin, and staring at the tapestry flashes back to 10 years before.

Matthias' poor village is invaded by the rats of Cluny the Scourge. His sister Myrtle manages to escape a fire with him, and begin a trek away.

Official Synopsis
Matthias the mouse is orphaned when the vile rat Cluny the Scourge destroys his township. Adopted by the generous creatures of Redwall Abbey, he grows up to admire their legendary protector, Martin the Warrior. But his dreamily peaceful young life is shattered when the Abbey is attacked by rats and Matthias meets their warlord-- none other than Cluny! Matthias resolves to fight the tyrant that once again threatens his life-- and new family.

Differences from the book

 * Matthias' entire back story, including his sister Myrtle, was not in the book.
 * Time is measured in years instead of seasons, as Abbot Mortimer describes Matthias as having resided at the Abbey for 10 years, and being age 13.
