Matriochka

Requires: Minecraft 26.3, 26.2, 26.1.2 (one jar for each), Fabric Loader, Fabric API and GeckoLib. Install on the client to play solo, on both server and clients to play together.

The wonders can be found and are worth finding: the worlds' people point at them, every relic gives its world's gift, a group shares the reliquary, and the Journal draws a map of every world.

Wonders and relics

• The people of every world speak of its wonder: one greeting in two, while its relic is still to be found, they say in which direction it stands and how far. The Journal's world card keeps what they said.
• Every relic gives, besides its heart, a gift of its world: the relics of Worlds 1, 2, 5 and 7 make Toxin, Heat, Noise and the loss of breath a quarter slower (World 10 has all four rules); the others give luck in chests, faster attacks, safe falls, speed, less knockback or faster mining. The ten together add 4 armour.
• A reliquary opened by one member of a group gives its relic to every member standing within 24 blocks, straight into their inventory.
• The Last Candle is rebuilt as a great wax candle in a ring of open arches, and the Sleeping Giant as a giant lying on its back, face to the sky, moss grown over it.

Journal

• A map of every world, from the world's card: the ground walked through inked in the world's colour, the places found drawn by role (people, combat, exploration, story, secret, wonder), the player as a small doll, and a legend of what has been found.

Music and sounds

• Each of the twenty lesser biomes has its own variation of its world's theme, in the same mode, with its own tempo and lead instrument.
• New sounds for the reliquary opening and refusing a key, for a relic taken in, and a quiet air near a wonder.

Checks

• The game tests check that every world raises its wonder inside the group's parcel and that a relic eases its world's rule.
• The CI's game runs on Minecraft 26.3 start at last: it gets a software Vulkan device beside Mesa's OpenGL.
