Built by me and some other people originally for a Finnish Minecraft server as a hub in 2015, it served it's purpose and after being retired over a year I thought I'd finally put it to good use.It's a huge and complex space-station with rooms, from where some might be empty and up to you to design (or redesign everything) for whatever use you might put it in. It can work as a RPG map, as a hub or whatever your brain put it into. Use your imagination! Reddit thread from when it was built - it has been a while. Credit to the other people too who helped me with it.
