Azkaban

An ancient castle stood in the waters of the North Sea, absent from both Muggle and wizard maps.

According to investigations, the castle's master had been a wizard named Ekrizdis. People generally believed that the castle lay within a space created by his magic.

The castle's master had been immensely powerful, but he seemed to have been mentally unstable. He would always use magic to lure passing sailors and crewmen, then torture them.

He took pleasure in it.

By the time Wizards later discovered the castle, its master had already been dead for many years, and the castle should have become an ownerless place.

Yet countless Dementors had been born there, monsters that fed on human souls and positive emotions.

The Ministry of Magic dispatched many people to investigate and study the place, but in the end, they could only conclude that the Dementors could not be driven away and had an unknown, inseverable connection to the castle.

Any attempt to damage even a single brick or tile of the castle would provoke the Dementors' frenzied retaliation.

The investigators were unwilling to reveal anything further. They only said, "Every wall of this castle is steeped in torment and suffering."

Later, the Ministry of Magic requisitioned it as a magical prison, known as—Azkaban!

Every Wizard imprisoned here would gradually lose all positive emotions, leaving only endless pain and oppression.

Therefore, no one locked up here would remain mentally sound.

Almost no one came here to visit prisoners, because they did not want to see people they knew in such a deranged state, nor could they endure the terror of this place.

Dementors usually could not distinguish criminals from passersby. They released darkness and terror upon every living thing that approached them.

"Kid, I hope I'll see you again, hehe..."
