"Lonely men are we, Rangers of the wild, hunters -- but hunters
ever of the servants of the Enemy; for they are found in many
places, not in Mordor only.
If Gondor, Boromir, has been a stalwart tower, we have played
another part. Many evil things there are that your strong walls
and bright swords do not stay. You know little of the lands
beyond your bounds. Peace and freedom, do you say? The North
would have known them little but for us. Fear would have
destroyed them. But when dark things come from the houseless
hills, or creep from sunless woods, they fly from us. What
roads would any dare to tread, what safety would there be in
quiet lands, or in the homes of simple men at night, if the
Dunedain were asleep, or were all gone into the grave?"
