Place it at the start of the boss reveal, after Enemy Spotted and before the Inception Horn, so the entrance builds in stages. If the fight ends in a sudden defeat, follow it with the FNAF Jumpscare Scream for a sharp contrast.

This 15-second clip takes its name from Soul of Cinder, presenting a short, dramatic game moment built around a looming final-boss presence. It feels tense and heavy, with a slow sense of dread that makes a scene feel larger and more serious than before. It works best as a warning that something powerful is about to arrive.
