Recently, a friend asked a favor of me. He wanted to know if I could hold onto something for him, but he couldn't tell me what it was.
Turns out it’s an ancient scroll that fell out of his teacher's atache case. The teacher hadn’t realized it fell out and my friend was all set to give it to him when he noticed it’s malign content. After reading several lines of the scroll he realized that it contains a powerful spell with which the caster will command all of the forces of the underworld to effectively take over the world.
He couldn't be sure what the teacher's intentions are with the scroll at this point and so he needs to keep it out of his grasp. Therefore, he elected to hide the scroll at my house putting my family in danger of being attacked by whatever malevolent forces are out to get this powerful talisman. The jerk.
