Irradiated Power Crystal is a crystal that was part of the crashed ship, the Exodar, a piece of Tempest Keep hijacked by the draenei in their flight from Outland. The crystal fell into the Silverline Lake in Ammen Vale on Azuremyst Isle. Unfortunately, the crystal's radiation is wreaking havoc on the local wildlife, causing mutations and sickness, and infecting the water table due to its position in the lake. Luckily, the draenei Botanist Taerix has developed a [Neutralizing Agent] that may be able to stop the radiation, at least temporarily.
