The Mithril Barrier
2330
The wizards of Azimere, always the isolationists, make the rare move to claim Thave territory as their own. The wizards then erect a massive magical field of energy known as the Mithril Barrier between themselves and Thave. The blood witches of Thave launch many attacks against the barrier and the wizards themselves, but Azimere is too strong, and the barrier stands defiantly across the red desert.
