They're triggered by a chain of critical events. Unlock the clues and count down those final Seconds from Disaster.
Equestria. > Canterlot > The Royal Wedding. The royal wedding is a happy time for married couples to live happily together. In Canterlot, this is to be true with Twilight Sparkle's brother, Shining Armor and Princess Celestia's niece, Princess Cadence. 12:30 PM. Twilight Sparkle receives two letters regarding their duties for the wedding. They hop on board the Friendship Express to reach Canterlot and arrive to find strict security measures in place. 1:10 PM. Once in Canterlot, Twilight shares her anger towards her brother for his failure to mention the wedding. 1:25 PM. Princess Cadence arrives, paying attention only to Shining Armor. 2:00 PM. Twilight Sparkle peers into a door as Princess Cadence and Shining Armor chat. She sees Shining Armor getting a spell poured on him and is convinced Cadence is evil. 3:21 PM. Practice for the wedding takes place and Twilight makes a statement and Cadence darts off upset. 3:36 PM. Cadence returns and sends Twilight Sparkle down below to a cave. 3:55 PM. Down below, Twilight Sparkle unleashes her anger on Cadence, whom has indeed gone evil, and finally breaks open the wall containing the good Cadence. 4:15 PM. The actual wedding ceremony has begun but is stopped when Twilight Sparkle and good Cadence arrive. 4:22 PM. Evil Cadence reveals herself as a changeling and orders some of her army to attack Canterlot's overhead defenses. 4:40 PM. Celestia wages a battle against this new being but loses.
Now, by rewinding the events of that day, and going deep into the investigation, we can reveal what went wrong at The Royal Wedding. The first question on investigators' minds is why didn't anyone notice the arrival of this being and her army? *Shining Armor comes on screen*
"We were all so focused on the wedding preparations that I guess we didn't keep watch outside," said Shining Armor.
What about this being? Who is she and where did she and her army come from? *Princess Celestia comes on screen*
"We don't know for sure but I believe she was from Tautarus and have no knowledge of her name since she never gave it herself, though rumors have stated her name is Queen Chrysalis," stated Celestia.
With the origin of Queen Chrysalis in place, the next task is to figure out where her power came from. *Princess Cadence come son screen*
"She was gaining power from my love with Shining Armor," answered Cadence.
Even so, why wasn't Princess Celestia able to stop her when she has defeated past foes with ease? None of the footage investigators view is able to answer that question. *Twilight Sparkle comes on screen*
"It's possible that Queen Chrysalis' magic is more current than Celestia's and therefore Celestia's magic isn't able to hold back as much as it did before," figured Twilight.
It's the final piece of the puzzle. Investigators can now reveal what went wrong during The Royal Wedding. 6 hours to disaster. With everyone inside, no one sees the impending arrival of Queen Chrysalis. 3 hours to go. Since no one realizes Queen Chrysalis is disguised as Princess Cadence, Chrysalis, willingly sends Twilight Sparkle below ground. 1 hour to disaster. Twilight Sparkle arrives above ground but since Princess Celestia's magic is older, it isn't able to hold back Queen Chrysalis' more recent powers and loses.
After the disaster, the ponies have since thrown out Queen Chrysalis and her army while having a perfect wedding finish. They are all now better aware of any threats that may come from the outside and will be on the lookout with better security to prevent any future intrusions.
