Twizwick Sprocketgrind

Twizwick Sprocketgrind is a Goblin who lived in the mountains nearby the Venture Co. mines, at Mulgore. 
Even though he was bit crazy, Twizwick is a very ingenious engineer, who always wanted to have an apprentice. He loved Mulgore, but the Tauren did not seek to learn the ways he mastered. However, his chance to teach someone came with Ramaka, a young troll that somehow reached his hidden house. After insisting for hours, Twizwick taught the troll the ways of engineering, finally getting the apprentice he had always wanted.
