Take the orphan to the bank of Darnassus. The bank itself is hollowed out of a tree known as the Bough of the Eternals.
I've heard stories about how the night elves have their bank in a tree - one that looks like a bear! That's so cool! Night elves are neat how they like nature and stuff, but bears are just totally awesome!
Would you take me to see the bear-tree in Darnassus, please? There's a boat that will take us close to there, and it shouldn't take very long. Please, please, please!
