'In the Black Riders' wake, crebain have taken roost. They are not the common strain from Dunland, but a breed I have not seen before. Likely these foul creatures keep watch on Buckland and Shire...or at the very least me, since they have taken to staring at me in the night.
'While the crebain may see nothing of interest, the fact that the Enemy has eyes here is dangerous. If we were to blind these eyes, the Enemy would not be as sure in directing its efforts. If you would, dispose of the crebain that roost to the south-west, just beyond my camp.
'Even killing one craban will go a long way towards blinding the enemy.'
Desiring news about the other Nazgûl, Strider sent you west to the borders of the Shire and Buckland to speak to Lenglinn, whom he had sent to look after a hobbit.
The crebain have taken roost south-west, just beyond his camp.
Lenglinn told you that crebain followed in the wake of the Nazgûl and have taken roost outside his camp. He is sure the birds are the Enemy's spies and will report on movements in the west. He has asked you to dispose of them to prevent them from doing harm.
Lenglinn's camp is to the north-east of the crebain roost.
With the crebain dead, the Enemy has fewer eyes watching Buckland and the Shire. Speak again with Leglinn and learn what else he would have you do.
'Good, you have slain those foul birds! The Enemy will not be nearly as sure in their efforts now!
'However, I still have need of your aid. I must ask that you do something in Buckland, as it was their Horn-call that alerted me to the presence of the Nazful.'
