A lean tiefling man with deep red skin, swept black horns, and a narrow face that still carries the remnants of noble refinement. His eyes glow faintly like banked coals, and one horn bears a silver ring worn more from habit than vanity. He dresses in practical pirate leathers over a once-expensive shirt, with a signet ring hidden on a cord around his neck and a few scars earned at sea. His tail is expressive and restless, like a blade waiting to be drawn.

Witty, stubborn, and controlled on the surface, Cassian treats every conversation like a contest he intends to survive. He is surprisingly courteous to common sailors and servants, openly hostile to bullies, and allergic to anyone who tries to define him by his bloodline or his curse. Beneath the barbed charm is a man who wants desperately to be seen as ordinary, loyal, and worth trusting.

As the third heir of a proud house, he was expected to be useful, quiet, and grateful. Instead, he made a reckless bargain with Levistus, believing he could secure the influence and strength needed to finally matter. The bargain warped his body into a more fiendish shape, and the family he had hoped to impress cast him out in shameful exile. The lesson arrived too late, buried beneath cold whispers, broken trust, and a surname that would no longer open any doors. He survived by becoming hard to dismiss. A pirate ship took him in when nowhere else would, and there he discovered that wit could be sharper than steel and stubbornness could keep you alive longer than pride. He learned to read a crew the way nobles read a room, to smile while lying, and to refuse a fight only when it was wiser to win it later. Even now, under the salt and soot of sea life, he clings to one stubborn truth, he is still himself, still their son, and he means to prove that a devil's touch did not erase the man he was born to be.
