Hmmm many things I have been thinking.
1. They didn't make another TGH book about Star and Morningleaf and the rest?
2. Brackentail and Morningleaf become mates?
3. Bumblewind didn't die?
4. TGH message board didn't exist?
5. All the pegasi from the beyond were freed and alive again?
6. Star became the destroyer?
7. Rockwing was alive?
8. A TGH movie was created?
9. Echofrost and Hazelwind didn't leave Anok?
10. TGH didn't exist?
Sorry if I scared you with any of these XD
