The huge owl blinked in wonder at these young owls. They seemed to know nothing. And yet…He let the thought trail off. Certainly their survival skills must be pretty good if they got out of St. Aggie’s. Still, there was no education like the one he had received. The education of an orphan. The orphan school of tough learning. He had to learn it all himself. How to fly, where to hunt, what creatures to stalk and which to avoid at all costs. No, nothing could compare to figuring out on one’s own the hard rules and schemes of a forest world—a world with uncountable riches and endless perils. It took a tough owl to figure it all out. And that was exactly how Twilight thought of himself. Tough.
