Posalon is a worldbuilding server where players make nations and build up a shared history. It has been active for over a month and the community seems focused on lore and politics.
Right now there is a WWI style war going on with the Republic of Sunlindia and The Hokagenate fighting the KOTO coalition. You can join a side and fight or you can start your own nation anywhere and do your own thing.
Movecraft is the main plugin so people can build tanks planes ships and submarines for big battles. The server also uses Brewery X plus lands and a guns plugin. It supports crossplay for Bedrock and Java.
