Descartes Isle is currently controlled by Narya.


Descartes Isle is named for French mathematician René Descartes.

On a stone to the east of the market reads, "This island were fashioned by Mnemosyne".

The Descartes Isle navy was initially named "Somerset Navy" rather than "Descartes Navy". The name was changed in the first few days of the ocean.

Along with Lincoln Island, Greenwich Island, and Wensleydale, Descartes was one of the original four colonized Sage islands.

When Sage originally opened, there was no direct route from Descartes Isle to Kashgar Island (the route was from Cook instead). This was changed around March 7, 2006.

Descartes was transferred from Narya to Death's Banner on September 15, 2006 in preparation for the "Who wants to be Hades' Governor?" event.[1]

There was a Distillery building, which has since dusted: Brimstone Brewery.
