In any city, in any country, go to any construction site or foundry you can get yourself to. When you reach the overseer, ask to visit someone who calls himself "The Holder of Work". The overseer will sneer and assault you with a barrage of hideous truths. Do not react and restate your request. He will ask you to wait for a second, as he has to call his boss; at least that's what he says. He will then leave. Wait for a minute or two, then a person will walk beside you. He will ask you for "The Holder of Twins". Tell him that the worker is currently away, talking to his boss. Tell him that both of you will have to wait until the warden returns.
