Imperial Dimension Neptunia (IDN) is a mod that aims to bring the fun of Neptunia to RTS format! It takes place in an alternative version of the Imperial Remnant era from Star Wars Legends. Imperial Dimension Neptunia overhauls and rebalances the Factions of Empire at War and even adds the Planetune Empire. Lots of new units from the Neptunia universe are added too. Neptune, Noire, Iris Heart, Kurome, Kurumi, Tohka, will also appear to fight various mighty Empires!
Palpatine from the Dark Empire story in anime form.
After thought to having been killed by Vader on the second Death Star, Palpatine returned to try and bring back the galaxy under the Imperial Banner.
More than likely Palpatine will remain exclusive to skirmish mode, maybe he will eventually appear in a Dark Empire themed GC.
