Well you should know that, yes while our birth element (meaning the element that is placed with us on our birth year) is the element that most people focus on, but it isn't the only element we can work with. We can work with all 4 of the elements, but we can't control them. Sense the element have been around a lot longer then us, they are very powerful and ancient.
(just so you know, so that you don't get confused).
The animal guide (or spirit animal) that will help you when you need it, well there is no real spell for that, you spirit animal will present itself to you, when your meditating in the forest (there are probably more ways, but this is the one I know that works best for people).
If you are looking for good books I know that Lark will know good books to start your way in learning about Wicca.
