"Mr. Sharma, thank you for your candor." Wizet spoke slowly. "At least under the current circumstances, even wizards mainly rely on containment when dealing with Dark Magic creatures."
"Especially Dark Magic creatures like Dementors. In fact, Dementors are on a higher level. Like Peeves, Boggarts, and other Dark Magic creatures, they are classified as 'non-beings.'"

Malcolm Sharma raised an eyebrow in confusion. "You can actually mass-produce these unkillable monsters?"
Wizet nodded. "Yes. Cornelius Fudge, the former Minister for Magic of England, once did
