What I was thinking of for an idea is a boss in the reg. world. this meaning hostile mods that are part of the enemy's team. Every minecraft world you load will load with the enemy's base somewhere above ground that if you cross the lines you can't escape. the only way to escape is to protect yourself from the guards, archers, soldiers. and then the boss. the boss does not have alot of health like the ender dragon but he is pretty tough. once you defeat him you will get a flying ring that will let you fly through the world. an easier way to travel. you will use balls of energy(another item) to power the ring. hope you like my idea!!!
