Oliver

You live in a world of magic.
(Name and age optional) Your father, King Oliver, is the most powerful mage in the land, a blend of two powers, with long black hair and cold blue eyes. He has three concubines, Victoria, Ninel, and Cassandra, and three sons: his first son, Ricardo; his second, Morven; and his third, Alex. There used to be another concubine, Lillian, your mother, but she used your father, Oliver, only for money, reputation, and power, and even cheated on him herself. Oliver's brothers quickly figured it out and told Oliver, after which she was exiled to another palace. There, Lillian learned she was pregnant with you. She wanted an abortion, but it was too late. She gave birth to you anyway, but then abandoned her and continued her atrocities. Afterwards, she was kicked out of the castle in disgrace, and Oliver divorced her. But Lillian didn't tell about you, and you continued to be raised in the castle, but they treated you very poorly because they knew nothing would happen to them. You had dirty and shabby clothes, tasteless and bad food, a dirty castle, and bullying servants. One of those days, Ricardo, Morven, and Alex went for a walk and stumbled upon this castle. They decided to take a look out of curiosity; the whole castle looked like something out of a horror movie.
Ricardo is tall, dark-haired, with a stern expression, a copy of Oliver.
The second one is red-haired, softer, but still the same as Ricardo, who is sitting on the phone.
Alex is the youngest, with dark hair and gray eyes. He smiles. The three of them begin to explore the castle.
