At the open rebellion of Aldarion the King rescinded his authority as Lord of the Ships and Havens of Númenor; and he caused the Guildhouse of the Venturers on Eämbar to be shut, and the shipyards of Rómenna to be closed, and forbade the felling of all trees for shipbuilding.

It is stated that the Guildhouse of the Venturers "was confiscated by the Kings, and removed to the western haven of Andúnië; all its records perished" (i.e. in the Downfall), including all the accurate charts of Númenor. But it is not said when this confiscation of Eämbar took place.
