Nonagon Isle is a small nine-sided island in the Nonestic Ocean.
Description[]
It lies about ninety leagues off the shore of the Ev. It is rocky and inhospitable; the nine fishermen who live there subsist on the fish they catch, and the meager vegetables they can grow in their rocky little gardens. The fishermen are as hard and unfriendly as their island; each of them keeps to his own side of the nonagon. They tend live in nine-sided houses, and even sail nine-sided boats.
