I miss the green, I'll admit. There was a lot of rebuilding to do in Narnia when we first began. The Witch didn't care for places where too many Narnians could gather together. Too much opportunity for rebellion. She'd also driven out or killed all humans at the beginning of her reign. Not all of their descendents wished to return, but those who did needed homes.
I didn't really appreciate either of my parents until after Narnia: what it was for Father to leave us all or Mum to send us away.
