Caulin's eyes were on the book before him.
When he first came across the book, its information had automatically entered his mind.
As if it warned those who wanted to use it of its price.
Yes, this Mystical Artifact had a side effect. One had to pay a certain price in order to acquire the knowledge they seeked.
The said price was a pact.
Depending on the importance, rarity and impact of the answer the user was looking for, one would have to sign a certain pact with the book.
The price was bearable in the sense that the book displayed the agreement to you before giving you the answer, making it your decision if knowing the answer was worth entering into a covenant with the Mystical Artifact.
However, once you entered into a contract with the book, you had to complete it by any means, else the price was your death. Certain death.
Caulin didn't think that simply asking for the title of the person would have a heavy price.
