Who killed it?

Moments later, the dagger materialized in his hand. The blade's polished surface gleamed under the dim chamber light, casting faint, fleeting reflections onto the surrounding walls. Silas gripped the weapon tightly, feeling the perfectly balanced weight of the hilt in his hand. It was as if the weapon had been forged for him and him alone. He shifted his stance instinctively—his right foot sliding back to anchor his position, his body coiling like a spring. With a sharp exhalation, he swung his arm forward, unleashing the dagger with precision and all the strength he could muster.

The blade sliced through the air at a velocity so rapid it became nearly invisible. Its whistle was sharp and fleeting, marking its deadly trajectory. It struck true, embedding itself deep into the golem's skull with a sickening crunch. The creature's immense frame shuddered before collapsing to the ground.
