Twilight is searching for a book that a customer was looking for, only to find one she's never seen before. In fact, she sees more. around 4. They are labeled: Player's Handbook. Monster Manual, Dungeon Master's Guide, and D&D Campaign: Baldur's Gate.
After investigating, she finds that this is in fact a role-playing game, and decides to play it with her freinds.
What she will later find out, is that this is no ordinary game.

Author's Note: I won't put things in my story like (Perception check: D20... Success!/Fail.) all the time. I'm only doing that in the prologue. Thanks!

Note: I did not make the picture. All thanks goes to danosix on deviantart.
