The dark figure radiated a suffocating chill, as though it could swallow all light. A single glance sent a shiver deep into the heart, and fear surged like a tide.
Harry was closest to the door and bore the brunt of it.
He faced the dark figure's indistinct face head-on.
The figure opened its mouth and pressed it to Harry's, as though sucking something out of him.
Harry instantly felt his consciousness blur as darkness and despair consumed him.
He wanted to cry for help, but no sound came out.
Lupin sprang to his feet, apparently about to intervene.
But Hermione was faster.
"Expecto Patronum!"
Hermione swept her wand, and dazzling silver light burst from its tip.
A spectral silver otter charged at the dark figure, radiating warm light.
As though confronted by its nemesis, the figure gave a shrill scream of pain and immediately released Harry.
It turned to flee.
But how could Hermione let it get away?
The spectral otter instantly transformed into a curtain of light, enveloping the entire figure to form a huge sphere.
Inside the sphere, the figure thrashed wildly in every direction, but could not break through the barrier of light.
Like a trapped beast, it let out desperate howls.
Under Hermione's control, the sphere gradually shrank.
From its initial diameter of two meters to one meter, then to the size of a basketball...
The figure was compressed relentlessly inside the sphere, its struggles growing weaker and weaker.
Bang!
A muffled explosion rang out.
Compressed to its limit, the sphere became too much for the figure to withstand. It exploded on the spot, dissolving into countless wisps of black vapor.
Peace returned to the compartment.
