The Mnemosyne Fleet (pronounced NEM-oh-seen) is a Pelesetian city-fleet. The ships of the Mnemosyne Fleet have taken the concept of a city-fleet to its inevitable conclusion and connected many of their craft into Pelagopolis, a floating city anchored near the sunken remains of the island of Peleset. Other Mnemosyne ships usually remain near Pelagopolis or within the Akrotirian Isles, rarely venturing much farther afield within the Chaska Sea.
The crews of the Mnemosyne Fleet are known within the Union for their desire to remain closely connected to their former homeland. More conservative than other fleets, the people of the Mnemosyne Fleet travel less widely and are rather more sedentary. Though they retain the characteristic hospitality and acceptingness of the Union, Mnemosyne crews are largely descended from the initial Pelesetian refugees, in large part due to their relative lack of connections to far-away places. Still, Pelagopolis remains open to all friendly visitors, Union or otherwise.
