Herefara has found that the map contains markings for an old fortification called Flodgeheld. It seems likely to have been attacked by the White Hand as was Brockbridge.
'I have been able to further study the map you found. I determined that one of these markings represents an old fortification called Flodgeheld, which lies to the south-west of here along the Swiftwater River. We have not heard from the men who guard it for some time, and they are likely in trouble, have abandoned it, or are dead.
'Please follow the river south-west and find out what state Flodgeheld is in, and if there are any survivors.'
Flodgeheld lies along the Swiftwater River to the south-west of Brockbridge.
Herefara has asked you to go to Flodgeheld.
Flodgeheld lies to the west of Brockbridge.
Flodgeheld appears to have been attacked by the forces of the White Hand. You should scout the area for survivors.
An injured Rohirrim appears to have hidden himself near the old palisade.
You should speak with the injured Rohirrim and learn what happened at this place.
One of the two slain Rohirrim you found earlier should have supplies that would aid Wilberth, the injured man you found.
The healing supplies you found will stop Wilberth's health from declining due to the injuries, but it will take some time for him to fully recover.
Wilberth would like to thank you for your aid, as he would probably have died not too long from now without help.
