Here are some free online resources if you're interested in knowing about canon better. Whenever we discover a new good one, we'll update here!
The entire Chronicles of Narnia on audio for free(legally!): http://www.learnoutloud.com/Free-Audio- ... 5901#plink
You may have to try the "listen to podcast" link a few times. For some reason it occasionally brings you to the wrong recording. It's a lovely recording, though.
WikiNarnia: http://narnia.wikia.com/wiki/The_Chroni ... arnia_Wiki.
We do not recommend making WikiNarnia your primary or final resource. It draws information from the movies and conjecture without always citing, which means it can sometimes be in conflict with actual canon and/or NarniaMUCK canon. However, it can sometimes be useful when you've got nothing else to go to.
