Tog Rustsprocket is a gnome located in Kharanos in Dun Morogh. When a Level 10 warlock talks to him, he'll have a conversation text (ie, not a quest) that says: Then if you select "What message?", he'll direct you to Lago Blackwrench. Lago will offer you the warlock only quest: File:Alliance 15.png [10] The Slaughtered Lamb, a quest chain leading to learning the Summon Voidwalker spell.
