The dwarf frowns and says, "Them brews be fit for kings, men or dwarves, a finer treasure you'll never find! Gold can be stolen, steel rusts, but the taste of a fine brew stays with you the rest of your life!"
After his outburst the dwarf tugs thoughtfully on his beard and says, "Though I can see how you might see it as being a bit much to risk your life over a drink. I can't say what rewards I can offer you, but the Lord's treasury is said to be full of gold, rare metals mined from the earth's bosom, and magical artifacts. If'n he lives he will surely reward you richly. I'm sure the invaders have valuables as well. I can say at least that you can keep whatever you take off them.
Speaking of those foul creatures, you are probably right in that they were Hobs. They carried no lights, so they could see in the dark. They had allies though, some were tallfolk like men, and there was a least one real biggun in with 'em."
