The letter N is hard-I couldn't think of any remotely cool words that start with N-Then I continued to think (having nothing more useful to do except write an essay on fraud, which incidentally I finished at 4 this morning!)
Anyways, here's my list of N words (some of them may be phrases and, in fact, not even English!)
If you want a letter to play the game then reply to this post and I'll try to remember my alphabet (with the help of the useful keyboard in front of me).....

Neverland-We wanna be like Peter Pan, we never wanna grow up!
Narnia-talking beavers, friendly lion, Perpetual snow, evil queen, random mystical creatures of no particular description- I wanna sit as queen in the castle of Cair Paravel!
