The Fey Realm is a truly magical place, where imagination and arcane prowess mean more than the laws of physics. It's rare that a mortal can stumble into the Fey Realm, and even rarer for a fairy to venture outside of it, but a demonic invasion is a spectacle no fairy would want to miss. Keeping that in mind, the Fey Realm has its own colorful cast of characters to choose from:
Glisten of the Unicorns
Glisten, the former wife of dragon king Rixl, was a ruler of the Unicorns, who held magnificent magical strength. Using her powers, she gave herself a beautiful, glistening coat (hence her name) and the ability to transform between her natural, quadrupedal unicorn body and a two-legged form more appealing to mortals at will. She even cursed her cheating husband until he went into hiding. However, her powers did not exist without a cause. Soon, Glisten realized that even though all unicorns were quite flatulence (seeing that they had the bodies of horses), her gasses were the worst amongst them all, and got worse as she used the arcane arts. Feeling a bit ashamed, Glisten secluded herself into her enchanted palace, but perhaps one day she would return to the outside for a truly special occasion.
Titania of the Fey Dragons (Special thanks to Marshmallow)
Long ago, some dragons stumbled into the Fey Realm, and their immense physical strength was warped and turned into magical power. Titania was the leader of this clan of dragons, and still ruled over them even after their transformation. However, her transformation also changed her draconic greed into a strange desire to spread love and happiness across the world, and a demonic invasion might just get in the way of that.
Marshflower: The Emissary (Special thanks to Marshmallow)
Marshflower was a messenger from Queen Titania. He's one of the first Fey Dragons born in the Fey Realm, and his joyful mood and desire to spread happiness reflected that perfectly. However, he's not as strong as his older peers, and so when he's staring down the barrel of a demonic invasion, he might just be more vulnerable than he'd realize he was.
Blossom and Marie: The Twins
Blossom and Marie were a pair of non-anthropomorphic, regular horses who accidentally stumbled into the Fey Realm, and were granted the gifts of magic, speech, and higher though as a reward. Not entirely familiar with the ins and outs of the Fey Realm, and more than a bit curious of the brand new world of understand that a sapient mind offered, Blossom and Marie became a pair of "witches" living deep in the Miasmian woods, traveling back and forth between the normal world and the Fey Realm, and sometimes leaving travelers stranded where they don't belong, as a prank of course. The demonic invasion might not interest the two, but the influx of inexperienced Astrean crusaders certainly would.
