Nova and Jack
I've taken us up to the edge of the marshes just past Ost-in-Edhil. It is a place the Elves called Nîn-in-Eilph (Swanfleet), where there were once great flocks of swans who lived there.
If the group looks back east they would see the Hithaeglir, the Misty Mountains that we crossed from Lorien.
NIN-IN-EILPH
Erkaliel has pointed out two swans to Tanroth and Erfalas.
From the marshes we should turn southwest - we will come to Tharbad (mostly deserted now - but I'm sure there are still Men living about the area who would sell us horses), where the Old North-South Road crosses the River Mitheithel and leads up into the western part of the Shire.
