We're building out several different types of voxel port connections.
Right now, military aircraft and ships (sailing vessels, modern vessels, etc) will be going between the major public areas. There are ships on the docks at Old World Spawn and New World Spawn.
Because we have moved "New World Spawn" (to the southwest quite a distance), we now have 3 different areas that are or have been spawns. We'll be naming each of these to differentiate, then put up signs to mark them.
I will be putting docks in at Spawn Castle (placeholder name for the castle across the bay from where you currently spawn.
The USS Hornet is far to north (If you know where the Star Destroyer is on the map, it's north of there. This will be the transport hub for all public areas via aircraft.
Right now, either Port Stanley, Port Moresby, or Midway Island is going to be the surface ship travel hub.
Star Wars craft will be able to transport between the different Star Wars places... right now, just the ISD is set up.
Final Fantasy style airships will be used to connect remote mountain tops. Right now, there is only one (The Cliff Racer, at Tyrael Air Station - might be Tyrael Airship Station in the future). These will always be in far-flung areas, please do not build within 128 meters of them. The point here is to set them up to allow travel to the frontier areas so people can get back and forth as well as skip known areas when scouting for a new place to build. You can find Tyrael air station south of NWS, and north of current spawn (northwest of Infernals new work of art). This will be to only station somewhat near habitable areas, to give people a jumping off point to the farther flung locations.
Private voxel ports can be purchased as discussed long ago, and they can be whatever you want, but they need to be consistent (i.e., if you want to make a ship on one end, you need to make the receiving end make sense... i.e. a ship, or a dock.
Rune portals are all up to you, just do not place them in public areas unless inside a public area building designated as yours or your groups.
You may connect into any of the public hubs, but know that doing so is bi-directional. Also, your connecting port object (ship, helicopter, etc) needs to match the hub type, and if you are making an airship, it needs to be remote.
