Fluttershy has been sent with Rarity to talk to the deer on a mission of peace. That goes well enough, but then she is told she is expected to learn from the deer about her strange new magic. Then Trixie and Fluttershy's stoic sister show up. Discord also shortly makes an apearance, trying to convince them go into the depths of the deer's wood. However this isn't the end of strange guests as the so called blood flutterponies show up. In fact it seems like the problems never stop, and then to top it all off there is some big event in Canterlot to attend at the end of their trip.
