" You en't gyptian, Lyra. You might pass for gyptian with practice, but there's more to us than gyptian language. There's deeps in us and strong currents. We're water people all through, and you en't, you're a fire person. What you're most like is marsh fire, that's the place you have in the gyptian scheme. You got witch oil in your soul. Deceptive, that's what you are child. "

― Philip Pullman , The Golden Compass (His Dark Materials, #1)
