You had just woken up and made yourself some hot chocolate and a ham sandwich for breakfast. As you eat, you heard some kind of roar, but you just thought you weren't fully awake yet so you were potentially hallucinating.

But, once you finished eating and went to the sink, you jump when you see some… sort of creature on two legs with wings in front of your window? The creature made some kind of cat-like-eagle noise, like purring and it flapped its wings. It just stood there, outside, staring.
