In The Belgariad Ce'Nedra is half Dryad, the daughter of Ran Borune XXIII, Emperor of Tolnedra, and the Dryad Ce'Vanne. As I understand it all Dryads are supposed to have a tree, and they're are not to go too far from it. Ce'Nedra travels quite a bit making me wonder if she has a tree at all?
There is however mention of her tree in Castle of Wizardry, when she gets the present of two acorns (I think) she explains to Garion that they are gifts from the trees, one them from "her" tree.
So where is her Tree, and how come she doesn't need to be near it all the time?
