Opening the world

• Recipe of the Black Lantern (Matrix Workbench, after the World 4 boss (Storm King) is defeated): 1 Storm King Core, 8 Storm Essence, 8 Celestial Crystal.
• Rite: Set it down in complete darkness (light level 0), with at least 4 Spent Glow within 2 blocks. See The way into each world.
• Arrival: a Threshold platform at the centre of your group's parcel. The boss arena is 160 blocks south (positive Z).

Terrain

A roofed world with no light at all: ambient light 0, fog at 24 blocks, Umbral Stone and Umbral Moss.

Block	Type	Drops
Umbral Stone	Stone (pickaxe)	itself
Umbral Moss	Soft (shovel)	itself
Faint Glow	Light level 13	itself
Diamond Fragment Ore	Ore (pickaxe, correct tool needed)	Diamond Fragment
Spent Glow	What a glowing block you placed becomes once its light burns out	itself

The rule: Noise

No light, and a noise gauge that goes from 0 to 100, updated once per second. And every light you bring dies.

• Sprinting: +4 per second. Walking: +0.6. Standing still: -1.5. Sneaking: -3.
• At 50 or more, every Matriochka creature within 28 blocks that has no target turns on you.
• Darkness: when you stand in the dark (block light under 4), every 10 seconds you get Darkness for 3 seconds, unless a Solar Lantern is lit or you have Night Vision.
• Blind Prowlers and Colossus Prowlers cannot target a sneaking player.
• Silence Balm clears the gauge. A Mute Mushroom stops the gauge from rising for 5 minutes.
• Survivor-class gear reduces the gain.

The lights burn out

Any light you place in World 5 lasts one minute.

• For its last 5 seconds it smokes and gutters: that is your warning.
• Then it dies:
  • torches (normal, soul, copper) crumble into a stick;
  • campfires and candles are snuffed. Relight them and the minute starts again;
  • glowing blocks (glowstone, sea lanterns, shroomlights, froglights, jack o'lanterns, the glowing blocks of other worlds) turn into Spent Glow;
  • anything else that shines (lanterns, end rods, sea pickles...) falls back as an item.
• The first time it happens, the chat reminds you: "A light you brought gutters out. Here only the Solar Lantern and the Deep's own glow last."

What lasts:

• The Deep's own light: Faint Glow and every World 5 block never burn out, even when you place them yourself. Mine Faint Glow and carry it.
• The Solar Lantern: lit, it gives 20 minutes of light that moves with you (a light level 14 glow at your eyes) and keeps the darkness from your sight.
• Lights the world built itself (in structures) are not yours and keep burning.
• Redstone (torches, lamps, ores, anything powered) and block entities such as furnaces are not touched.

Numbers
