(Right, time to talk about spells. You can cast any spell you like with your arcane demon-caused sorcery, but the problem being that there's a random chance your powers will simply not work, or even backfire. Spells can only be used in specific circumstances or have specific uses, and have a recharge time, however they will always work.)
You read the whole thing. You learn a lot of things.
A lot of bad things you really didn't want to know.
Such as the fact that your universe lies on a razor's edge, in an infinite multiverse. The concept of a multiverse is already pretty bad (If you think about it), but it also turns out that your universe is entirely likely to die at any second due to an invasion by either an insane anthromorphic summarization of madness and chaos in a spiffy trenchcoat or something wearing a black cloak and a bone-white plague doctor's mask. Both of them do not have very nice goals for humanity. You learn a few things, though. An arcane spell that the book says will be highly useful, for instance.
Red Death
History: This spell was made by the worshippers of the Green Eyed Man, a multiversal god of chaos. While the Green Eyed Man prefers to use his own disease (The Undying Plague), when he is not around the worshippers use the Red Death, a combination of every disease into one megavirus.
Use: Using this spell will cause the target to become infected with a horrific disease. They will degenerate into shambling horrors dedicated to sharing their plague. However, using this in combat will result you unable to use the next turn.
Recharge Time: 10 turns.
Shuddering, you stumble out of the shop and head down to the better shop. By the time you arrive, it's thirty minutes later. It's a long walk from your apartment to the main part of town. You head into the supermarket and look around for the weird cravings the whisperers require. You find basically all of them (Excluding the souls), piling the random items into a trolley and heading to the counter. The clerk scans the items then looks at his computer. "Right, $87.99 dollars, sir." He smiles at you.
His accent is vaguely Mexician, if you're (Or they're) curious, and you're (Or they're) in America. Still doesn't solve the problem...
