I woke in the middle of the night. I look around as I yawn, the room was organized and tidy. I suddenly get cold like someone had put an ice cube on me. I look towards the window and realize I had left it open. I go over to shut it but see someone shivering below the castle. I am high up, so I use my weak magic to open the window. I fly down to the pony. In my surprise, though, they are not a pony. But instead another changeling who seem's to have escaped the forest. His name was Thorax. He was hurt really bad and I didn't really know what to do. I ask if he's okay, but all I got is a groan of pain in response. I grabbed him and flew him into my room. He is very grateful that I saved him. Many ponies in the town of Ponyville were not accepting of changelings. Which obviously made sense.
I see blood dripping on the floor, and find the source. I moved Thorax's wing to find a tree branch had impaled him in the lung. This had gone beyond my medical knowledge and I placed him on my back. I ran off to find some pony to help. I know there is a mini-hospital in the castle for the Princess and her guards, so I look for that. I didn't know how much time I had till Thorax bled out.
I eventually found the place and the nurses that took Thorax back. All I could do was wait now.
