My slab would be made from the dried and sown together faces of a thousands slain enemies, constantly shifting and contorting, all arranged in layers so that the least-threatening would be on the outside, while the most hideous on the inside. Inside this thick protective coating of ever-shifting flesh would be a single blood-stained stone of steel.
Well, it's a great conversation piece. ~ Citizens on the Slab of Bloody Murder.
It would bestow exactly three terrible curses.
The curses it would bring upon you would be three - no more, no less. The number of curses that shall be upon you if you do not return it shall be three. Not four or two, or any other number, but three. Three is the number of curses that shall be upon you. Exactly three. Not three and one tenth, but exactly three. ~So it is said and that's how it shall be.
The first curse shall be a powerful warning. From the mountains shall descend a rain of fish. And it shall rain fish for 40 days and 40 nights, not a second more. This period will provide such numerous amounts of fish that entire countries will be buried underneath the hail of fish and all those billions of fish that land shall be not only inedible, but also invincible, flopping around for an eternity.
The second curse shall be a plague of giant rabbits that shall cover the surface of the earth and destroy most human life in the process, wiping out all thinking life along with them and remaining the rulers of earth, completely backwards in the time and space continuum.
The Final Curse is one most foul. There will be a single hard to reach spot on your body that will constantly feel like it needs to be scratched. And every time you reach for that spot, it will become more and more itchy, constantly moving from one place to another nver letting you scratch it. Oh, and a meteor drops on the world, but that's not as bad.
I'd consider stealing it, but that last curse really put me off.~Thief on Slab of Bloody Murder.
