Graphomantic Crystals

Crystals found in the sewers of the dream veil in Sanctuary. 
Graphomantic crystals are capable of animating and transforming a variety of materials, so far, the party have found they seem to bring life to objects and materials:

• Glass
• Gems
• Cloth
• Stone

These are stones from a bygone era that were once refined into graphomantic salts to be infused into buildings and to power Arc Batteries.
