Lets see...Deep Magic, Deeper Magic, Nature Lore, Animal Lore just to name a few...Not to mention "The Prophecy"..."The First Joke"...
Its also gonna have stuff that normal MOds have, like Horseback riding, and seafaring for the non-animal civs like Calormen or Archenland
Its a fantasy MOD, so it will have a fantasy style tech tree...I already have it drawn...older versions have been posted in the past, but I dont know where the newest version is...
and to answer your last question, Im not trying to follow the story too much...just making a MOD in the flavor of Narnia...not like my SG-1 scenario, which walked you through the story line...
