The Lich's Identity

There is a lich who dwells on the island in Brightwater Lake to the north. Although he is a free-willed Forsaken, he believes all other Undead are Scourge slaves and has his minions attack anyone who approaches him.$B$BBut because he is Forsaken, the Queen will want him. And if he is skilled in Necromancy, then his knowledge would be...quite useful to us.$B$BTo discover his identity and his talents, I must see his spellbook. Steal into his camp and acquire it, then return to me.
