Oleander

Oleander resembles a classical unicorn: she has a long spiral horn, bushy fetlocks, cloven hooves like those of a goat, and a leonine tail. Prior to corruption from reading the Unicornomicon, she was white with light blue highlights on her mane.
After the corruption, her coat turned light grey, and her mane became black with bright pink highlights. She gained purple hooves and eyeliner, as well as darker grey eyeshadow. She wields the Unicornomicon at all times. Unchanged from the corruption, her horn and the inner sides of her ears are light lavender, and her eyes are blue. As additional accessory, Oleander has purple glasses.

Oleander can be best described as a troubled teen: she's long been known as the Order of the Horn's resident rebel. She's snarky, arrogant, and won't hesitate to directly insult her opponent, but shows a softer side for puppies and doughnuts. Oleander also cannot stand her peers' closed-minded philosophy of Light Magic prevailing over everything. She believes that Dark Magic can be used for good and is determined to prove it. Oleander cares for nothing but saving Foenum from the impending threat of the predators. She thinks she's smarter than everyone else.

13 turns of seasons before the incursion of predators, when Oleander was younger, she found the Unicornomicon, although it's not known how long she's had it for. One day, after reading a portion of it, her coat turned dark. When Oleander arrived at the Sacred Grove, she was scolded for it, as it proved she had been studying the forbidden Dark Magic. After being told to go back to her room, Oleander wanted to burn the book, but FHTNG stopped her and said she'd be the one to save the world. Oleander, interested piqued, was convinced by Fred to keep studying the Unicornomicon and forging a pact with him.

Arizona is a stupid, uncouth redneck cow. She needs to understand that her brute strength is nothing compared to my knowledge and dark magic. She's my rival.

Velvet is a princess of reindeers fixated on her beauty. Her ice magic is so boring and monotonous. She's my rival.

A weak, cowardly lamb with adorable cute puppies that I just adore! It would have been better if she had sat in her fields and kept her head down. She's my rival.

Longma is a half-horse, half-dragon with martial arts and fire magic. Her kung fu is nothing against my dark magic. She's my rival.

Annoying absolutely stupid, insane and unbearable alpaca, who loves to hug and kiss everyone. She's my rival.

She's a pirate goat. A nimble, fast thief with water magic. Let him hunt for his useless glitters when the main wealth is knowledge and magical power. She's my rival.

Her favorite accessory is glasses. Her favorite treat with Fred is donuts with strawberry frosting with sprinkles, deep fried. Loves puppies. Unlike other tea drinkers, Oleander liked coffee with a lot of sugar.
