| The land of Tharbad is almost flat, with sluggish waters tending to spread into fenland. Above Tharbad the river forks, with both branches having converged from out of a network of swamps, pools and eyots. It is populated by swans, and many other waterbirds. This huge fenland north-east of Tharbad, which the elves named 'Nîn-in-Eilph' or Swanfleet. Near the Swanfleet is a ford over the Glanduin, from where leads a road to the ruins of Ost-in-Edhil, the ruined city of Eregion.
Tharbad was the only settlement of Númenóreans in Enedwaith, because the area beyond the fortified town was of little concern to them, except for the patrolling and upkeep of the Great Royal Road. To this end, a considerable garrison of soldiers, mariners and engineers kept there until the seventeenth century of the Third Age.
In the years of the Great Plague, traffic along the road through Tharbad has declined considerably, as many parts of Eriador had become desolate during this time.
