With this seed you will start your adventure in the middle of the ocean, surrounded by 1000 islands (of course, there are actually fewer islands, but it feels like so many of them). Feel like a seafarer exploring islands and fighting drowned. Not far from the spawn, at coordinates 120 ~ 120, you can find an unusual generation: a monument above the ocean ruins.
