Radagast the Brown is assisting the Elves of Mirkwood in mending the forest and cleansing it of shadow.
'This wood is to be Mirkwood no more, but Eryn Lasgalen, the Wood of Greenleaves. Though our foes both far and near are overthrown, the scars and shadows they have left behind will not willingly give up their grasp upon our home.
'No, there will be hard work in the greening of our wood, and we are thankful to name the wizard Radagast the Brown our friend, for his knowledge in such matters runs deep.
'In fact, it had nearly slipped my mind, but when he arrived at Felegoth, he asked after you by name. You ought go and meet him. I believe he is in the tree nursery outside these halls, just now.'
