Invisible and untouchable, their mastery of the sky was unrivalled till sauron's ringwraiths took to the air upon the backs of fell Winged beasts during the war of The ring. Even the Dragons of old could not match their aerial prowess, and so keen was their sight that they marked even the stirring of a mouse upon the mountainside. Orcs tread openly on the slopes at their peril, and wards kept to the deep forests where trees shielded their passing. In the days of the third age The mightiest of the eagles was gwaihir the windlord. Friend to Gandalf the grey, he bore The Wizard upon his back and more than once flew to his aid when great need called.
