I have made a 1.13 starter world and would like everyone to have it. It is small but OP and helpful. Do not mind it is saying 1.11 there's no 1.13.

A large secret base, figure out how to get in and explore all the wings, comes complete with a large mob grinder, drop detectors, many farms, a secret vault, and more!

Our vanilla server world

my world has a train station, a bomb range, three or four houses and lots more!

Just a test

this land is full of graves and there is a hole in front of one which leads down to about 40 graves underground!

My main world, done with no cheating (except for some ice and a dog spawner, but that doesn't really count). It is much more impressive in gameplay, as with all worlds. There is a huge pillar (5 X 5 open air) that leads all the way from the top (almost, not quite done) to the bedrock. There is an automated minecart system down to it. Overall I am quite happy with it, but no where near done!
