What are you talking about? We have a brand new SmallWorld map on the server...
You not being able to mine was a permissions issue, it has been resolved. So you should be able to get all the materials you need.
Once you do you can go anywhere you like in the Spawn world, or visit one of the other worlds through the portals on the central island. I think you will find that the Spawn world is kinda like a Skyblock world but without the Skyblock restrictions. You can create towns there and have access to more materials. I'm excited to see what people will do with that world
