Background:
Princess Harmonia Shine, or just Nia for short, is the daughter of Princess Twilight Sparkle and Flash Sentry.
As a filly, when she heard stories of how her mother and her friends saved Equestria, she was in awe! However, given how great her mother is, Nia felt she needed to be just as great, especially since she was born an Alicorn like her cousin, Flurry Heart. This lead to her being insecure about her being an Alicorn, considering she hadn’t accomplished anything great to receive her wings like her mother did.
To bolster her spirit, Tempest Shadow took Nia under her metaphorical wing as her squire. It wasn’t until she entered a great battle to defend Equestria alongside her friends that she got her Cutiemark.
Now Nia has a dream to form “The Knights of Harmony”, a group of knights of various races dedicated to defending against anyone wanting to disrupt the harmony that her mother and her friends worked so hard to create.
