DragonHawk - Hidden Dragons
Legendary Stone of Fairie
On the material plane, if you have sole control of the stone, you can cast limited wish.
On the Faerie plane side you have the power to open portals to the material plane.
This greenish, jade-like rectangular stone, two feet long, 1 foot wide and tall, radiates immense magical power. TI is engraved with a Celtic knot design that crisscrosses the stone in multiple directions. The lines of carved depictions of knots separate the stone into equal sections, each fully symmetric with each other. Despite its size and density, the stone weighs very little (probably a product of previous wish)
