There is a big world that is designed exclusively for construction. There is also another world in which you can extract resources and create anarchy.
There is a system of portals that can send you where you need it for in-game currency.
For convenient sorting of items there is a special plug-in.
So that you do not lose things on the server there is a plugin that will collect all your dying things at the place of your death.
Of course, nobody wants to start all over again every time, so the server has a whale system.
