NarniaMUCK

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.

The Power of Poison: http://www.amnh.org/the-power-of-poison
This is more an RP resource than a Narnia one, but still extremely useful! An interactive book on poisonous plants from the American Museum of Natural History, healers can learn a lot about several plants we have in-game, and other players can learn a few to avoid.
