New Prematon Island is an island on Puraeon discovered in 2010 during the events of Codename: Video Game Caper, with a city being built between 2010 and 2055, when Codename: Downfall of Steam takes place. It is named after Prematon.
Originally, New Prematon was just a village connected to Prematon via the Forest of Wonders. See the outdated article on New Prematon on the VGC2DFOS Wiki for more information.
