Elias, a freelance data recovery specialist, squinted at his monitor. A link had been sent from an anonymous burner account:

He ran the link through a sandbox environment first. No viruses. No trackers. Just a single, massive PDF file. He clicked download.

On page 404, the blueprints stopped. In their place was a single grainy photo of a handwritten note.

“Elias, I didn’t run away. I uploaded. Help me compile.”

He knew he shouldn't click it. In his line of work, unsolicited files were usually digital pipe bombs. But "Nayanathara" wasn't a common keyword in his circles. It was the name of an ancient, forgotten star—and also the name of his sister who had vanished three years ago.
