Black Rocks

Black Rocks are the crystalized essence of magical energy. Previously found in abundance and aggressively mined, they are now very rare. As a result, they had been highly sought after items. Typically their presence will cause headaches and mood changes among people who can cast magic. In large enough quantities they can cause magic users to fall unconscious.

Appearing as black gems, they give off an oily light. When the magic is used up and drained from the rock it has a more translucent appearance.

High Queen Isilda believes the rocks to be an evil form of magic. Furthermore, she speculates that the world can be saved by cutting off the power to the stones. However, the exact source of their power is unknown.

Discovery under Orcha
Following the defeat of the Oblex in Orcha, a large black rock was discovered. It is believed that the Oblex may have been feeding off the power of the rock.

When news got to Sebastian Stahl that a large rock was now unguarded in the abandoned City, he wasted no time in moving to secure it. Since then, his team has aggressively mined the rock, selling smaller pieces of it to buyers across Ozma.

Side effects
The rocks seem to have addictive qualities, with many people being unnaturally unwilling to part with them. In addition, the rocks seem to drain the life from people in close proximity to them, causing them to waste away. Specifically, people suffering from the effects of prolonged exposure report food having no taste. Others begin to cough up blood. Magical healing, such as Lesser Restoration, does not appear to reverse the effects of this exposure.

For others however, the side effects can be very different. It has been seen that the black rock can imbue tremendous power. Granting strength and new power to those in contact with it.
