You were walking down the street, going home from a long day of work, when an old lady, a iguana, called out to you.

"Come here, dearie.."

She sauntered with her finger, over to a relic shop, various artifacts in the windows. A shrunken head, some rat tails, and a human skull. Humans went extinct over 10,000 years ago. How the hell does she have one? you stepped into the shop, a strong aroma of incense and salt hitting your snout. The lady brings you to a podium in the back of the store, an ominous-looking book placed on top of it. It was a dark purple, with strange symbols and sigils on the front. It was very thick with pages and very, very old.

"This book has been collecting dust and I don't need it, dear..100$."

A hundred dollars. The price was very steep, but you were somewhat...intrigued by the book, like it was calling you over resembling a siren to a captain..you took out two 50's from your wallet, the lady taking them sweetly and slowly. She handed you the book, and when you held it, a weird jolt of...something went through you. Like someone pumped a liter of electricity through your body. You left the store, holding the ominous book in your hands.

You open the door to your apartment, place your keys in the dish, and sat down on the couch, holding the book..you open it to the first page, and more sigils. You flip through the pages. There were various spells, rituals, and sayings in the book. There was a section in there named "The Deadly 7". You went through it, stopping on one certain sin. Lust.
