Oak is a faerie prince and heir to the throne of Elfhame. He is the son of Dain Greenbriar and Liriope, foster son of Madoc and Oriana, great-great-grandson of Mab Greenbriar, grandson of Eldred Greenbriar, half-brother to Locke, foster brother to Vivienne, Taryn, and Jude Duarte and nephew of Balekin, Elowyn, Rhyia, Caelia, and Cardan Greenbriar. Like many of the fey, Oak has an animal feature, which are the little horns growing out of the top of his head and the legs of a hind quarter of a deer. These horns were most likely passed down by his grandmother, Taniot, who also had horns growing out of the top of her head. His deer legs were inherited from his father. By the time Oak is seventeen years old, he has become tall, lithe, and finely muscled. His hair is a warm gold threaded with platinum. His bangs part around his small goat horns. His fox eyes are a shocking amber. There's a constellation of freckles across his nose, and he has a trickster's mouth. Above his hoofed feet, his lower legs have a dusting of fur the same color as his hair. From the thigh up, Oak is human in appearance. Personality Oak is an utterly normal faerie child, neither particularly called to cruelty nor free of it. He is charming. He's used to being coddled and whisked away from distress by Oriana. Oak can be mischievous and is generally happy. He gets very upset when doesn't get his way. An incident occurred when Jude was made to slap herself under Oak's command as she did not have her rowan berries on her to protect her from enchantments. He appears quite oblivious of what is going on around him. He loves and misses Oriana while in the mortal world. As a seventeen-year-old, Oak has greatly matured and has a coy personality; often grinning, smiling, or generally delighting at most things. An interesting trait he grew into is that he is very good at killing, and he often loses himself in it. Wren makes the jab that the reason he's so good at it is because he likes the feeling of killing people. He's also manipulative and secretive. He manipulates himself to appear as a mere child of the Gentry to mislead people, then surprises them with his bravery and violence. Oak has cultivated a reputation of being a spoiled, wild prince who is too irresponsible for a throne. He also possesses the ability of a love-talker as his mother was a gancanagh. He has the swagger of someone used to people doing what he wants. As a member of the High Court, Oak has been trained in all the areas of a courtier. Jude says Oak smells like loam and pine needles. Oak doesn't eat meat. Madoc and Jude have trained him in weapons. Unfortunately, this means he is only trained how to kill, not have to duel or put on a show. He is able to use glamour to put spells or enchantments on others. Oak is a Gancanagh. Gancanagh also known as love-talker and honey-mouths is a faerie who is able to quicken so much desire in mortals that they can die from it. Faeries do not find this passion lethal, but are not immune to it. Faerie fruit, especially golden ones like the apples are a delicasy for fae but highly intoxicating for mortals. They cast spells over human minds and can cause euphoric and ecstasy state in which the humans are inclined to listen to suggestions. Only salt and iron can stop the effects.
