- Description from Novelupdates

When you're reborn as Jorah Mormont you ain't got much. A Dad looking to bale and go spend his days hanging out with the guys on the Wall, a wild Aunt raising your wild cousins you can't stand, an arranged marriage to a girl you never met with a dowry almost low enough to be an insult, and a populace of smallfolk so inebriated and incompetent its no wonder nothing's changed around here in 8,000 years. Hopefully the gold finger granted by Levid's Magically Wheel of Reincarnation can help.A really nice pair of testicles.With that, the right attitude, and a shovel I have everything I need to dig a nice grave to lay in.Or Bag End. Let's see which happens first.

“Finally, the owner has appeared. You read me.”The Archmage’s legacy, the Book of Truth.Binair Dalheim, a dropout of the Elfenbein Tower, accidentally discovers the Book of Truth.“I will awaken your magical talent. In return, complete me.”The dropout boy, whose dormant talent has been awakened, begins his journey to retrieve the Book of Truth as requested.

Afterlife wasn't something that he had thought about, or maybe he had, the downside of being thrust into a new world with your memories wiped and having no recollections of any dreams was disorienting....but then again he chose this path, now in a sexualized version of the original novel. How much can magic, which depends on strong emotions could be driven by Lust and Desire?Warning! The story contains and centers around Smut, there is plenty of plot to go around, but if you want to avoid the smut entirely, it might be a little difficult!!
