The secret of the mansion

"When you're hearing this, I have passed away. Honestly, I don't want to place this burden on your shoulder, but there is no one else who can. If you don't want to continue, press Stop."

10 seconds later...

"So you choose to accept. However, do your wife really want to share this fate with you? I'll give the two of you a minute to discuss. If Becky doesn't agree, press Stop."

1 minute later...

"Hm, so Becky agreed too. But what I'm about to tell you can -and will- change your life forever. Think carefully. If you're not so sure, press Stop."

30 seconds later...

"You passed the point of no return. Now you can't leave anymore..."

A loud "BLAM!" sounds behind Roger and Becky. They turned back, only to find the door of the conference room shut itself. Becky clings to her husband's arm: "Now I start to be afraid."

The tape continues "...but you don't need to be afraid. This mansion can provide you everything. My vast wealth is just a tiny application of its power. In fact, I think what it can provide is only limited by our imagination..."

Roger and Becky: "You're joking!"

"...that's what I predict you'll say. No, I'm not joking. Or perhaps I'm? What the mansion can provide is also limited by the first rule of the universe: Equivalent Exchange..."

Becky whispered: "That is what you called eccentric? I think he's crazy!"

"...you may think I'm crazy. I don't blame you: I used to think so too when my great uncle Sirius leave this mansion to me. I changed my thought when hearing the origin of this mansion, which I’m about to tell you right now:

Once upon a time, one of our ancestors has built this mansion by magic. It can collect power from lust, and fulfill all desires. However, he quickly found that his heaven is, in fact, hell. He became a prisoner of his own creation. There is only one way to get freedom: Someone willingly receive it from you.

I still have a lot of things to tell you, but time won’t allow. You can find the rest in the diary in my bedroom. For the last step...”

The cassette player suddenly exploded. Among the craps, there is a ring which is made entirely from a material look like ruby, and there is a note below the ring:

"Wear this ring, and recite the creed as follow."

Roger puts the ring on his finger and begins to chant:

"In desire day, in horny night,

__With loving hearts, our bodies combine,

__Let those who try to stop what's right,

__Beware my power — lust made into might!"
