Harry Potter and the Great Old Ones

"You...you guys?" Professor Frolov asked in a low voice, "Your research group is specifically responsible for this research?"

“You’ll see when we get there,” Mitchell McGann chuckled. “We started as a research group funded by a big shot, but as we delved deeper into our research, that big shot gradually revealed his true colors.”

“That is…” Professor Frolov asked, puzzled.

“We belong to a shadow society,” Mitchell McGann said, his face flushed, “with a mixture of excitement and agitation.”

"A shadow society?" Professor Frolov frowned.

She's not some little girl like Mitchell McGann.

Hallelujah Frolov is 54 years old. Born in 1942, he lived through the end of World War II and the Cold War, and is well-versed in all sorts of conspiracy theories.

Although at his age he knows most conspiracy theories are nonsense, he still believes some of them to be true.

He knew that there were many unknown organizations and forces in the world that operated behind the scenes, manipulating the world's direction and possessing secret powers.

“Yes, Professor, the Shadow Society we belong to is a mysterious organization,” Mitchell McGann confessed. “Our research group is merely a conduit for contact with the surface human society.”

"Is it the Illuminati?" Professor Frolov asked in a low voice.

“What is the Illuminati?” Mitchell McGann was taken aback.

"Not the Illuminati?" Professor Frolov was taken aback by Mitchell McGann's answer. "Then what exactly are you researching? And why are you hiding your true identities?"

"The information we can share with you at this time is that our current research focuses on various supernatural phenomena and mysterious forces of photoelectricity around the world. We are searching for mysterious locations and species that still exist today by using some documents left by our predecessors and folk legends."

"Have you made any specific discoveries yet?" Professor Frolov asked. "The Unknown Cardas," Mitchell McGann said in a calm voice.

"Unknown. Cardas?" Professor Frolov pondered the word carefully.

It's as if this word possesses immense magic.

After a moment of silence, Professor Frolov let out a soft breath and took another sip of the warm water that Mitchell McGann handed him.

"How much do you actually know?" Professor Frolov asked softly.

“There’s something I’ve never told anyone,” Professor Frolov said, leaning back against the soft cushions of his waiting room seat. “When I was talking to that Deep One, he mentioned a place and a word to me.”

“A place like heaven,” Professor Frolov said. “A place that exists in their mythology.”

"You found it?" Professor Frolov continued to ask.

“We’ve been there!” Mitchell McGann said with a hint of pride.

"You've been there?" Professor Frolov was taken aback by Mitchell McGann's answer. "What do you mean by 'you've been there'?"

Professor Frolov's heart skipped a beat as he stared incredulously at Mitchell McGann. They had actually been to that mythical place?

How much knowledge in this world is there that he doesn't know?
