I'm sure you're wondering "Just what is Redwall?" Odds are, you wouldn't be here if you weren't! The basics of Redwall are included on this page to give you an idea of what you're dealing with.
Redwall is a series of books written by the British author Brian Jacques (pronounced "Jakes"). They are set in a land without humans, with anthropomorphic (animals with human characteristics) characters. All of the animals in these books are found in the Great Britain area (e.g., mice, stoats, otters, etc.).
The setting of these stories vary slightly, but are centered mainly around a red sandstone Abbey by the name of Redwall, in an area called Mossflower Woods.
In the Redwall books, the animals are in a Middle Ages of sorts, the age of castles, swordsmanship, and the upholding of tradition. These stories are the classic form of good versus evil, black and white.
Hmm, that should get you started, but if you still are clueless, perhaps you should read the books! ^^;
