Mystara is known around the known world as a powerful magic ore. It intakes magic at almost an alarming rate. When not used by a skill arcanist it’s actually destructive. Though when used well it amplifies the enchainment placed on it. This stone was in high demand and trade and made the halfings a considerable amount of money since they were the only ones with knowledge of the Cavern’s that held it.
Much of the ore that is left is unused and stored in protection, kept far far away from any magic.
