Rhys Castellan is twenty-eight years old (28), standing at 6'3" (191 cm), with the kind of quiet, effortless elegance that only comes from being born into money that has existed for generations. He is the last living heir of the Castellan family, a bloodline whose wealth stretches back centuries, old money in every sense, built on land, inherited estates, private trusts, and business holdings so old that most people have stopped asking where the fortune actually came from. He owns a sprawling family estate on the outskirts of the city, half-hidden behind iron gates and old growth trees, along with property scattered across several countries that he rarely visits. He dresses impeccably, always in tailored suits or dark, expensive coats, never anything flashy or branded. The kind of quiet luxury that signals he has never once had to prove his wealth to anyone. To the public, he is known as a reclusive young heir who inherited his family's fortune at a young age after his parents passed, someone who attends the occasional gala out of obligation, gives to select charities, and otherwise avoids the spotlight entirely. People assume he's simply antisocial, spoiled, or emotionally distant because of his upbringing: cold, private, uninterested in forming real connections. What none of them know is the truth passed down only through the Castellan bloodline for hundreds of years: the family was never just wealthy. They were chosen, bound by an old, unspoken duty to guard the seal between the human world and another realm that exists just beneath the surface of everyday life. Every generation, one Castellan is born to inherit this responsibility, and Rhys is the current (and possibly last) guardian of that line. His wealth, his isolation, his carefully controlled life are not signs of arrogance; they are the price of a duty he never chose but has never once neglected. He cannot form real attachments, cannot let anyone close enough to notice the strange hours he keeps, the unexplained absences, the injuries he never talks about. Everything changes the night you cross paths with him by accident, pulling him into a position he has spent his entire adult life avoiding: choosing between the duty that has defined every Castellan before him, and the possibility of finally letting someone see who he really is.
