Here be dragons

I'm in a city, it's as usual made of long houses interlocked with eachothers and very steep. I need to protect a small group of children from a man. I try to have them to run and get away, but they are too scared of stubborn to listen to me and I have to fight the man head on. I shapeshift into something quatripedal, with fangs and claws, attacking this man to keep him from snatching the kids. They run from me and I chase them into a house big enough to be a manor and scramble up some wooden stairs, shifting back and huddling in a corner between two dark rooms. I can see that one of them is a bedroom, with the single bed close enought to the half open door that I can see under it. I'm trembling all over, feeling both vindicated and hurt by the children's fear. My sister and a yound man find me here, and crouch to be on eye level with me, talking soothing nonsense.
The man take a halfstep to the left and a very strange insect crawls from behind him. It's a light, soft green color, and looks like a centiped the size of a small dog. On its head is a mass of feelers looking like ribbons or feathers, gently moving like algae in water. I'm both repulsed and fascinated by it, and I huddle a little closer to the wall when it advances. It stops before I get too inconfortable, and something grows out of it's back; it's butterfly wings, the same soft green color with a big eye-like spot and a long tail. It looks like a luna butterfly, and it's pretty, in a weird way.
