Great winter-worms have been interrupting the dwarves' efforts to get hot water from nearby springs. Weth is most annoyed.
'Will you help me? It's the most infuriating problem!
'We are trying to run water from the springs nearby to our encampment -- I want a hot bath! I don't think that's too much to ask, do you? Not in this unrelenting cold.
'Unfortunately, the great winter-worms have other ideas. Have you seen these creatures? Rather like furred drakelings, huge, heat-loving, cold-resistant, and very territorial. There are three water-channels in particular where they have disrupted our work. Please, in the name of steaming hot bathing-chambers everywhere, put a stop to this!
'You will find them north of here, where the water steams.'
You have made a dent in the population of worms around the dwarf-channels Weth described to you. You should return to him at Zigilgund.
