The D'irth Crystal
This artifact is an item of legend, a crystal ball that allows spells to be cast through it.
Quite possibly the most dangerous artifact in all of Sothis, The D’irth Crystal is a scrying tool through which spells may be cast, effectively making a spellcaster’s reach unlimited. Works as a crystal ball with telepathy, but is also a sentient item with a will of it’s own.
It is unknown what the source of the crystal and it’s powers are. The first mention of the item is in the records of the city of D’irth on the Forsaken Coast.
