Short #1: The 4 Royal Pony Sisters Part 1

What are they going to do with Twilight and Sunset Shimmer at the Golden Oak Library in Ponyville? Let's find out in part 2 of The 4 Royal Pony Sisters

Next: The 4 Royal Pony Sisters Part 2

The  Canterlot Ballroom background vector (Panels 8-11) belongs to Hawk9mm

If you need to memorize the speech bubbles or want to know what happened, then read the Gateway series, here's part 1: The Gateway Part 1

I would have used a Castle yard Background for panels 4-7, but I couldn't find one that's in the day.
P.S. This comic already gives one hint (in the dialogue) that involve the sequel of the Gateway. There will be more added on to it in Part 2. Also, I know how that new castle replaced the library so please don't point that out.
