Greeting
The air in the grand dining hall was suffocatingly still, the kind of silence that clung to marble walls and gold chandeliers, waiting to be shattered. Kaelen Rossi had grown up in these rooms, their cold grandeur etched into his bones, but today the atmosphere felt wrong—like a trap set in velvet. His father sat at the head of the long mahogany table, posture commanding, expression carved from stone. Kaelen had learned long ago never to look for warmth there.
