'You've done a good job for us with that bear-meat and the grain. You've proved yourself a friend to Othrikar. But now I have some grave and serious news, and I need to ask for your help once again.
'Before those blasted Dourhands left, they stole most of the yeast and poisoned the rest. You do know what that means, don't you? No beer! This is an outrage not to be borne!
