According to Barliman Butterbur, there is trouble in Buckland that could use your talents.
'A word if you've a moment, though if you're as busy as me, you haven't. What with all the troubles hereabouts, I think someone like you could be of help.
'There's trouble in Buckland, or so I've heard. Gates broke apart, Little Folk frightened, and worse yet, rumours of Black Riders in Buckland, like those seen moving through Bree. They say the Master of Brandy Hall is looking for help by way of his young niece, Celandine.
'Brandy Hall is atop a high hill in the centre of Buckland on the east side of the Brandywine River. Follow the road west from Bree until you see the Brandywine Bridge, then turn south into Buckland.'
The propery of Newbury is in Buckland. Follow the road west from Bree until you see the Brandywine Bridge, then turn south into Buckland.
