1 Lambert: Okay, so I guess we need horses?
2 Alvissa: No, the Dentorn Forest is too dense for horses. We go on foot until we reach the Badlands of Skrung.
3 Draak: What Draak eat, then?
4 Alvissa: It's an elvish forest. There are plenty of nuts and berries.
4 Draak: Ah. Elves then.

And you thought they used horses to carry supplies.

Well, I guess they do, in a way. Meat on the hoof, so to speak.
