Blackstone rune

A blackstone rune was a magical token used by shadow fey to transit between the Material Plane and the Plane of Shadow.
==Description==
It was a small glossy stone bearing a complex sigil.
==Crafting==
A blackstone rune was carved by a spellcaster who knew the plane shift spell and the art of crafting wondrous items.
==Powers==
The token allowed its bearer to travel from the Material Plane to the Plane of Shadow, or the reverse, as with a plane shift spell. They could take only 50 pounds (22.7 kilograms) of possessions with them. It functioned only three times.
==Users==
Shadar-kai weakened by their shadow curse used blackstone runes to take respite in the Plane of Shadow.
