Dr. Calballeron has betrayed his promise to Ahuizotl; so Ahuizotl turns to Daring Do and Rainbow Dash to stop Dr. Calballeron from obtaining what are known as the Three Sacred Treasures. It is with these three sacred treasures; which have been scattered to the farthest regions of Equis; that a person can control all the various temple guardians. Knowing that Dr. Calballeron has returned to his evil ways, it's up to Daring Do and Rainbow Dash to find and obtain the Three Sacred Treasures before Dr. Calballeron can or at least stop him from gathering all three in one place.
Bonus Genre (How do I have too many Genre tags?): Thriller
A/N: First off, this obviously takes place during the time period between Twilight's Coronation shown in the flashbacks of "The Last Problem" and the actual events of "The Last Problem" when not in the flashback to Twilight's Coronation. Secondly, while I would normally put "Alt. Universe" for something like this, everything that happens in-between what we see in the flashbacks of "The Last Problem" and the actual events of "The Last Problem" is left mostly open to interpretation. So that's why the Alt. Universe tag doesn't really work for this.
A/N 2: While Azuizotl is in the prologue chapter, he doesn't stick around for any longer then that. As such, he is not a main character.
A/N 3: This story and it's series has become cancelled. If anyone is willing to pick this up, feel free to PM me.
