In storytelling, exposition seems to be this necessary evil - you want and need it because people need to know what’s going on and why. On the other hand, you don’t want it because it’s alot of babble and often very boring – and you can bet that if you make it critical information, there’ll be plenty of people who actually didn’t listen. Onu willingly(?) steps up to be Mr. Exposition in most of chapter one, which puts him in the thankless role of being Mr. Boring. Though I guess big trees aren’t expected to be quick about things.
