Aragorn believes that Gandalf should be informed of the mysterious Sara Oakheart's theft of the palantír.
'Gandalf the Grey, currently in Bilbo's room on the first floor of the Last Homely House here in Rivendell, should be informed of the actions of this Sara Oakheart. You say you have encountered her several times before? Most curious.
'The theft of a palantír is no small matter, ${PLAYER}. Few have knowledge of them; fewer still can use them with purpose and accuracy. If this Oakheart is one of those few, her designs on such a powerful item bode very ill.
'Go now, and speak with Gandalf.'
