Radagast the Brown, in concert with the Rangers of the North, has journeyed east into the Lone-lands, seeking the source of a great evil.
'You have done much good for the people of Bree-land, but the Shadow out of Angmar spreads far and wide. I have learned from Gwaihir the Windlord that another of my order has found corruption in the Lone-lands, east of Bree. It may even be related to the dangers you encountered in the Great Barrow.
'Unfortunately, Radagast is given to wandering and will be difficult to find. I would ask that you enlist the assistance of the Rangers in finding his location. There is one here in Bree-land, Saeradan, who will be able to aid you.
'Head out of Bree through the West-gate and turn north along the Greenway. Seek Saeradan at his cabin on the east side of the Greenway across from Thornley's Work Site.'
Saeradan is at his cabin north along the Greenway in Bree-land.
Saeradan the Ranger might know where you should meet up with Radagast the Brown.
Candaith is at his camp in the Lone-lands.
Saeradan does not know where exactly Radagast was bound when he left the Ranger's cabin. He suspects that Candaith, the Ranger who watches the Lone-lands, may have information on the Wizard's whereabouts.
