Octavia Philharmonica, the Canterlot Conservatory's rising star, is about to begin a whole new part of her life; one that involves an old friend, an ambitious businesspony and a certain eccentric DJ.
The Royal Guard has intensified their training regimen after countless attacks on Canterlot. After months of hard training, they only accept the best of the best. Pipsqueak signs up to join these elite soldiers in order to protect a certain princess.
Twilight Sparkle is the newest member of Celestia's Royal Guard. Fresh out of the Military Academy, she's ready to prove herself, but will her first assignment be too much for her to handle?
Twilight is unable to control her powers during the entrance exam to the School for Talented Unicorns, and in order to reduce the damage caused by her power surges, Celestia shrinks her down until she would later learn how to control her powers.
