End Empire
The End dimension might be the only way for a group to create a genuine safe haven on 2B2T.
Normally, it doesn’t matter how many people you have or how strong you are. The moment any base of yours is discovered, it’s doomed.
There are countless griefers with essentially infinite resources and respawns. You could kill them a hundred times and it would only delay the inevitable.
That is unless you had some way to stop them from coming back.
It is impossible to set your spawn in the End with vanilla mechanics. You can’t enter the End except via a specific spawn area.
In theory, a large and rich enough group could go to the End and set up a sophisticated defence system and guard roster, so that anyone coming to the End is automatically killed by Wardens and traps.
That would allow them to create a truly safe haven - an End Empire. Even if someone slips through or turns traitor, all you have to do is kill them and they’re done. They’ll have to risk themselves at some point if they want to grief anything, and if they die there’s no way back in for them.
It would take a ton of organisation, resources, and probably at least two dozen active and well organised players.
But it’s possible. I’m surprised nobody has tried it yet.
