This story is a sequel to My Little Alicorn

After the events of "My Little Alicorn," everything seemed to be back to normal...except for one pony. Prince Blueblood is now trapped as a colt, his title, possessions and birthright stripped for his crimes. Before Princess Celestia will return him to normal, however, he must prove himself by attending Magic Kindergarten. Even worse, his current situation has attracted the vengeful gaze of two ponies he has offended in the past: the Captain of the Royal Guard and the Moon Princess.

Will Blueblood rise above his past self and emerge a better pony? Or will he sink back into his old depravity, and be stuck a colt for the long term?

Note: This is a sequel to "My Little Alicorn," so you might want to check that out first.

Monarchic Melancholy: The Reign of Blueblood the Beleaguered.

Prince Blueblood, least popular member of the Royal Family has rather confused sentiments regarding his role in society. However, the fates are never kind, and push him into a position which he neither wants nor feels himself suitable for.

All four Princesses suddenly go missing in the middle of the night. Prince Blueblood, Unicorn Prince, government functionary and paranoid cynic is instantaneously elevated to the highest rank in the realm, to the general dismay of both himself and the population at large. Against him are the arrayed forces of popular opinion, the noble houses, the Equestrian bureaucracy, Shining Armor, and incompetence, to say nothing of the impending threats posed by ancient evils and foreign powers. Overworked, bitter and panicking, Blueblood must attempt to keep Equestria in one shape - against threats from foreign powers, internal dissent or evil forces - until the Princesses return or are found.

Blueblood-centric, with heavy focus upon Canterlot life, politics, governance and intrigue.

Multiple POVs including Canterlot characters, the Elements of Harmony and OCs. Set after the end of Season 4.

Initially based upon an idea prompt by Nemospecific on the Give Blueblood some Character! group forums.

Luna has had enough of Celestia's games, and has found the perfect means of revenge. Using a long-forbidden spell, she transforms her sister into little more than a small filly, all so she could pull the greatest prank ever. Unfortunately, she soon learns that before you fool around with dangerous magic, you really need to read the fine print...

A sequel can be found here.

War comes to Equestria: with despair, with starvation, with suffering and with sacrifice. And the ponies must learn how to keep true to their values while surviving not just the rigors of battle, but the desolation of total war.
