Aelindil at Tornhad has agreed to help you fashion a weapon worthy of your skill as a Mariner.
'I wonder, ${PLAYER}. Is not a weapon yet another tool of navigation? It is true enough that one can guide you to the end of conflict or conversation.
'I can fashion for you a fine weapon, one befitting a Mariner of your skill, but first, I will need you to bring me a number of materials. I must warn you, though. This shall be no simple task, my friend.
'For your first task in this trial, I shall require two materials. First, I will need a cask of the foul fire-oil carried by the Orc, Throghásh, who roams near the ruins of Eitheldir, and second, I have need of a number of the steel water-flasks carried by half-orcs and brigands here in the Angle of Mitheithel. Despite our best efforts, they have maintained an encampment in the ruins of Thelgarth, so it will not be difficult to find them.
'After you have brought those to me, I will task you to find materials that must be gathered further afield, in less hospitable lands.'
