Aragorn's Silver Horn
The horn brought by the sons of Elrond to Aragorn so he could use it to summon the Dead Men at the Stone of Erech.
Then Elrohir gave to Aragorn a silver horn, and he blew upon it and it seemed to those that stood near that they heard a sound of answering horns, as if it was an echo in deep caves far away. No other sound they heard, and yet they were aware of a great host gathered all about the hill on which they stood; and a chill wind like the breath of ghosts came down from the mountains.
