The 9 gates of hell

Nathaniel's door.

Nathaniel took the middle door. Now, when someone summons Satan, he appears to you in a form you would feel most comfortable talking to. The only thing he can't hide, is that sinister look in his eyes. He can appear male or female
And usually chooses someone on the more attractive end of the spectrum. But the first rule always takes affect. You have to have someone that you can talk to. To Nathaniel, he appeared as his brother, Tommy. "Hello Nathaniel," Satan said smiling. "Tommy?" Nathaniel asked hopefully. "If that's what you want to call me," he said before switching to a non-distinct female, "Satan, Lucifer, or any one of the dark names work as well." Nathaniel was shocked. "I understand you're probably scared so I'll start the conversation," he said continuing,"I will grant you one wish, anything you want. For a small fee of course." "What is the fee?" Nathaniel asked needing to know. "You must either pass these nine gates and come face to face with me, a toll on your body, and entertainment for me, or you give me your soul. You can choose either, but if you're so mathematically impaired to pick the latter, well then you don't deserve heaven anyways."
"I will pass the nine tests," Nathaniel said, "and as for my wish." "Yes what is it?" "I want an infinite amount of money." "Deal."

It was then, Nathaniel made a pact with the devil.
