The Unicorn Fillies, oftentimes shortened as Unicorn, are one of the races that inhabit the Filly World. A large majority live on the seven islands of Crystalia, but a select few does not have a specified homeplace.
The main trait of the unicorn fillies are, logically enough, their long spiral-shaped unicorn horns on their foreheads. The unicorn horns are known to provide magic to an extent, but in contrast to several types of horse fiction over the years, Filly magic is not limited to unicorns or their horns. Both the horns and their Filly crown gems, are corresponding to the color of the gem that their family house is standing on, as well as to the color of their family emblem. There has also been reports that the gem also designates which of the six colors of the rainbow bridges that the Filly can stay standing on, instead of falling straight through.
They always use golden crowns, unless it's time to go silver, in which case their crowns are silver, or if it's a big wedding, in which case they'll be crownless. In the crowns of most Unicorn Fillies, are one colored gem. Princess Sparkle has a crown with five gems in multiple colors, one for each of the other islands connected to Iridia, as Iridia is the anchorpoint of one end of all five bridges.
Additionally, there's a higher than usual percentage of the Unicorn Fillies who decorate their manes with small flowers, especially among the residents of Glacia.

Other unicorn characters
Magic (character) boasts of being a true unicorn, as despite being a Fairy Filly with wings and everything, he does have a horn on his forehead, decorated with roses, and is rumored to possess very powerful magic. Him and Miss Magic does differ on that their horns have the same color as their fur.
