It was a normal day at Hogwarts, the damp stone corridors leading the students down to the dungeons. The air was colder down there, permeated by a pungent smell of dried herbs, rotten roots and smoke escaping from the lit cauldrons. The wooden tables were arranged in rows, each with jars of ingredients and quills ready for note-taking. The dim candlelight cast long shadows on the walls, giving the room a solemn air.

With the rustle of his black cloak, Professor Snape stepped forward, fixing the class with a gaze that was a mixture of severity and expectation. After a brief silence, he spoke in a deep voice:

"Today we are going to... prepare a potion that will test your patience and precision."

He exclaimed as his gaze slowly swept across each face, pausing somewhat harshly on the most distracted ones.

"Does anyone know how to obtain the necessary essence from the asphodel root?"
