A Bedrock Skyblock map with biomes and structure data, such as ocean monument for guardian spawning.

The layout is the classic known skyblock layout, with a main island with a tree, a sand island with a cactus and glowstone and mushrooms in the Nether.

Advancments are enabled.

Phantoms are disabled.

Seed

The seed is 487475928 and the map was generated in 1.26.3. Relatively near the spawn is a pillager outpost, a witch hut and an ocean monument. A bit farther away is a mushroom island, a jungle and snowy plains.

Generation

A 10,000 x 10,000 block square was generated using this plugin. It left some holes in the generation, so I modified the plugin to generate everything in the square. I then used amulet core in a custom script to fill every chunk with air, leaving the biome and structure data intact.  Bedrock Toolchest was used to clean up data, such as entities, tick data or chunks outside the square. 
So there was a fair bit jankiness involved. Feel free to write a comment if you find something off.
