Description
<name>, I received an urgent message from the High Examiner requesting your presence.
He's finally found something powerful-- VERY powerful--and he wants your help in recovering it.
Be careful down there, <name>. Tae'thelan can be a tad fanatical when it comes to artifacts that hold any sort of energy.
