Seer's Stone
A block of blueish granite polished to a mirror finish. The reflections in its surface move of their own accord, and you have an unshakable feeling that you are being watched.
Mechanics & Inner Workings
The stone is made from a several foot long slab of granite that was carefully extracted. Stones of various quality were created - the closer the stone was to the center, the less was needed for a clear scrying picture. They are items of unique origin, they cannot currently be recreated or duplicated.
Significance
These slabs of blueish granite are said to be carved from stone a mortal was standing on the moment they ascended to godhood.
Gazing into the mirror finish surface of these stones allows you to scry on any person whose name you know.
