There are lots of islands following each other in a straight line and your aim is to advance from island to island across the world using your cobbelstone generator. Each island contains a feature or represents a biome/structure.
This map is still being created and you may encounter some problems (say so in the comments) and not all the islands have been made yet. A story will be added soon to increase immersion.*
Background : You're part of the universe's police force. Your job is to ensure that worlds and portals work smoothly together. Recently, a group of looters opened a portal in the overworld leading to a dimension full of dangerous monsters that could well destroy your world. Your mission is to find “the red star”, a mythical object that has been broken and spread across many worlds in the time of the ancient builders, in order to close the portal.
Enjoy your trip!
---Spoil alert--- The screenshots may spoil parts of the map for you.
