Harry Potter: The Unqualified Hollow Knight

Hermione pairing (added so this wouldn't turn into a speedrun tutorial for Azkaban)

No mind capable of thought.

No will capable of yielding.

No voice to weep over suffering.

Baines only realized he couldn't become the Hollow Knight when he arrived at the Black Egg Temple.

Because the moment he understood what those three lines meant, it proved he had a mind capable of thought and a will of his own.

With no other options, Baines could only wander around Hallownest.

He followed Grimm and learned to perform, followed the Nailsmith and learned to make nail weapons, and followed the Mask Maker and learned to make masks.

He learned from every being with a mind, no matter who they were.

He even secretly followed the Radiance and learned from her.

But when he returned to the Abyss, it swept him away.

He ended up in a different world.

P.S. I just realized Voldemort had a pretty raw deal. He died, but none of his followers got into trouble.

They only got sent to prison after the Second Wizarding War.
