Soul Diamonds & Soul Forging

Invented by Elves in the age of darkness, soul diamonds are diamond shaped gems fashioned from soul crystal, the only material that can channel souls. They are used to trap souls inside of them. A common application for filled soul diamonds is forging them into weapons and other magical items and enchanting them. The souls energy (Ki) is harnessed by the enchantment and channeled through the item. This is called Soul Forging.

When a soul is captured, the diamond assumes the color/colors of that soul. Every soul has its own combination of colors which represent the innermost personality of whatever creature it once belonged to.
