Unicorns (Full name Filly Unicorn) is one of the races that inhabit the Filly Kingdom. They live in Crystalia, which has six floating islands:
All unicorn fillies have a single spirally-shaped horn that allows them to use magic. The horn's colour depends on the island that the filly is connected to, rather than the filly's coloration. Each of the families also possess a magical crystal that allows them to enter the interior of their island.
