What those caves are made of, by volume, measured from the save in 4 block cells: Shares are measured across the built map.

They are named from the blocks around the cave rather than read from the save. ## Structures 9 of 19 confirmed present. A pinned marker outranks the scan; anything not confirmed is what the scan alone recorded. Counted inside the built map. Past its edge the world keeps generating normal vanilla Minecraft chunks, so structures not confirmed here can still generate out there. ### Surface (1 of 7) - Desert pyramids: Not checked - Igloos: Not checked - Jungle pyramids: Not checked - Pillager outposts: Not checked - Swamp huts: Not checked - Trail ruins: Included - Woodland mansions: Not checked ### Underground (4 of 6) - Amethyst geodes: Included - Ancient cities: Missing - Dungeons / monster rooms: Included - Mineshafts: Not checked - Strongholds: Included - Trial chambers: Included ### Ocean (2 of 4) - Buried treasure: Not checked - Ocean monuments: Not checked - Ocean ruins: Included - Shipwrecks: Included ### Portal structures (1 of 1) - Ruined portals: Included ### Settlements (1 of 1) - Villages: Included ## Loot tables 29 of 37 confirmed present. Confirmed means the scan read the table out of the save. Not observed means the structure carrying it was not seen in this export, not that the table is impossible here. Counted inside the built map. Past its edge the world keeps generating normal vanilla Minecraft chunks, so tables not seen here can still turn up out there. ### Chest loot (12 of 20) - Abandoned mineshaft: Included - Buried treasure chest: Not observed - Desert pyramid: Not observed - End City treasure: Not observed - Igloo chest: Not observed - Jungle temple: Included - Jungle temple dispenser: Not observed - Nether fortress bridge: Not observed - Pillager outpost: Not observed - Shipwreck map: Included - Shipwreck supply: Included - Shipwreck treasure: Included - Simple dungeon: Included - Spawn bonus chest: Included - Stronghold corridor: Included - Stronghold crossing: Included - Stronghold library: Included - Underwater ruin (big): Included - Underwater ruin (small): Included - Woodland mansion: Not observed ### Village chest loot (15 of 15) - Village armorer: Included - Village butcher: Included - Village cartographer: Included - Village desert house: Included - Village fisher: Included - Village fletcher: Included - Village mason: Included - Village plains house: Included - Village savanna house: Included - Village snowy house: Included - Village taiga house: Included - Village tannery: Included - Village temple: Included - Village toolsmith: Included - Village weaponsmith: Included ### Archaeology (1 of 1) - Archaeology loot: Included ### Structure loot (1 of 1) - Trial chamber loot: Included ## What is inside - Biomes: yes - Structures: yes - Ores: yes - Plants: yes - Animals: yes - Loot: yes - Caves: yes Outside the built map the world keeps generating normal vanilla Minecraft chunks, so anything missing here can still be found out there. ## What is new - reverted / minimized masking of flows to biomes ## Questions about this world ### What is Advent Map 23? Advent Map 23 is a hand-made survival world of 3,072 × 3,072 blocks, made with WorldPainter, World Machine, Gaea, Axiom and WorldEdit, built for Minecraft Java 1.21.5. You download the world folder and play it like any other save, in singleplayer or on your own server. ### How big is Advent Map 23? 3,072 × 3,072 blocks, so about 9 million blocks of surface. Walking from one edge to the other takes roughly 12 minutes at normal walking speed. The terrain runs from Y -64 to Y 320. Outside that area the world keeps generating normal vanilla Minecraft chunks, so you never hit a wall, you just leave the built part behind. ### Which Minecraft version does Advent Map 23 need? Advent Map 23 is built for Minecraft Java **1.21.5**. Newer releases normally open it fine. Opening it in an *older* release is not supported: blocks and structures added after that version cannot load, and the world can be damaged by the attempt. Bedrock players need a converted copy. See [the Bedrock notes in the FAQ](https://mcmeddon.com/faq#install-bedrock). ### Which biomes are in Advent Map 23? 32 in total. The land is mostly Stony Peaks (18.8%), Plains (13.6%), Stony Shore (7.7%) and Wooded Badlands (6.9%), counted as shares of the land rather than of the whole map. Water covers 33.8% of the map, and land 65.9%. By volume this world's caves are Normal Caves (94.5%), Lush Caves (2.6%) and Magma Caves (1.4%). The [cave breakdown](https://mcmeddon.com/worlds/20251223-advent-map-23#caves) has the rest. The [full breakdown](https://mcmeddon.com/worlds/20251223-advent-map-23#biome-composition) is further up this page, with every biome and its share. ### Which structures are in Advent Map 23? 9 of the 19 structure types the scan checks are confirmed present: surface (1/7), underground (4/6), ocean (2/4), portal structures (1/1) and settlements (1/1). Not confirmed: Desert pyramids (not checked), Igloos (not checked), Jungle pyramids (not checked), Pillager outposts (not checked), Swamp huts (not checked) and Woodland mansions (not checked). "Searched, not found" means the scan looked and came up empty; "not checked" means it has not been looked for yet. [The structure list](https://mcmeddon.com/worlds/20251223-advent-map-23#structure-coverage) above names every one of them. ### Is Advent Map 23 ready to play in survival? Yes. A scan of the world file confirms loot tables, structures, animals and ores, so the survival loop runs from the first night: chests hold the game's real loot tables, mobs spawn as they do anywhere else, and you can mine, farm and build without adding anything. It plays in vanilla Minecraft, with no mods, no datapacks and no creative mode. The [world contents report](https://mcmeddon.com/worlds/20251223-advent-map-23#world-contents) at the bottom of this page holds the item-by-item detail. ### Where do I download Advent Map 23?
