The Ship-kings is a title given to the great King Tarannon Falastur and his three successors: Eärnil I, Ciryandil and Hyarmendacil I. The Ship-kings did much to expand Gondor's naval and military might. Between them, they enormously extended the South-kingdom's control over the southern lands of Middle-earth, including the lands west of the Mouths of Anduin, and as far south as the Haven of Umbar and the Harad.

If you like my Tolkien-related art, look at my related journal or gallery folder. But you can find even more of my pictures on my website Angrenost.cz. It's in Czech, but you can still look over the gallery of illustrations. Enjoy!
