Harmony rules Equestria. Twilight Sparkle is the new princess ruling from he new castle in Ponyville. Discord has been permanently reformed, King Sombra and Lord Tirek have been defeated, and Queen Chrysalis hasn't be aground for a while... but it is soon revealed that an ancient primordial evil of Equestria, which was believed to be vanquished millenniums ago, is on brink of returning.
Princess Twilight Sparkle is going to need more than just the help of her friends and the power of Harmony to combat the forces of Anger, Hatred, Doubt, Despair, Fear and maybe against even one's own... Pride.

Author's note: This story was previously known as Trial of Harmony and Order. I chose to reset the story and start from the beginning, hope you enjoy.

UPDATE 2021: More than 6 years ago I wrote my 1st story, which unfortunately lost steam due to a lack of confidence, effort, and just general inexperience, and on top of that I left the fandom altogether to pursue the creation of my own universe and narrative. With the series reaching conclusion I decided to come back and use what material the series has accumulated to try and write the story again. You can find the new one on Turmoil Rising.
