The Prodigal Lich

Bethor Iceshard, a high-ranking and powerful mage in the Undercity to the south, commands me to send him an agent with proven worth against the Scourge. You, <name>, will be that agent.

Present these orders to Bethor. He will then instruct you on your mission. I don't know its details, but it deals with recruiting a wayward Lich. And it will be dangerous.

So ready yourself, <class>. You must not fail.

You may find Bethor in the Magic Quarter of the Undercity.
