Atlas of the World
The Atlas of the World, or more commonly, "The Atlas", was a ship commissioned by Tallis the Elder in 1201, and principally constructed by Tallis the Younger. Construction was completed in late 1203, and the ship set sail on the Glasswater in early 1204. The Atlas was the largest ship ever constructed in the northern forests of Moregreen, and stayed afloat for exactly twelve days before sinking.
The original design plans for The Atlas called for at least one plank from each type of tree in the known realms, thus making it a product of the whole world, rather than just Moregreen. Similarly, the floors and walls would be inscribed with all of the known maps of the world, to both ensure that the ship never get lost and to ensure that the ship itself was a representation of the world.
Tallis the Younger was unable to secure transport rights for all of the desired wood, and thus the ship was constructed from only trees native to Moregreen. It is estimated that more than half of the forest of Moregreen was consumed in the construction of the shipyard, tools, and the Atlas itself over the two years of its construction.
Tallis the Elder's original scrolls are available for review in the Second Presidential Library, though sadly the scrolls containing the design for the Captain's Cabin were eaten by a pony in 1503.
At the time of construction, the Glasswater Gulf was connected to the Blue Ocean through the Mild Strait, what is now a landmass known as The Block. The original plan was for Tallis the Elder to sail through the Straits and visit all points of the world, with the Atlas serving as a beacon of peace and brotherhood for all citizens of Einwimz.
An earthquake in the final days of 1203 caused the Mild Strait to close, rendering the Glasswater Gulf into the Glasswater Sea. Undeterred, Tallis the Elder set sail from his son's shipyard and slowly approached the ruined Strait. The journey took a little over two days, after which the Atlas sat at anchor for a tenday.
On the twelfth day after launch, Tallis the Elder flooded the ship and sank it. No explanation for this action was ever recorded.
In modern times, "Sailing an Atlas" has become an expression used to symbolize a tragic or helpless undertaking. It is most often used to describe the affections of young men toward women above their station, as in "Jervy is sailing an Atlas for Miss Press".
