# The Thrum update

*v1.7 · October 2026*

The thrum moves stone. The last pages tell what the Shadow hunts.

- **[The thrum moves](#the-thrum-moves):** Heavers shift walls. Chutes pass stacks. Detectors keep watch.
- **[The Blastcharge](#the-blastcharge):** Lit by the thrum or a Flint. On the Riven Lands it breaks only your claim.
- **[Herds](#herds):** Fed, they breed. Led on a Tether, they follow.
- **[Hail and sandstorms](#hail-and-sandstorms):** Hail hammers the plains. Sandstorms swallow the desert.
- **[The Heart](#the-heart):** Isembard’s Shadow carries the last Torn Pages. Break it.

- **Clocks and notes:** A Hearth Clock for the mantel, a Vael Dial for the wall. Leave a note behind.
- **Your Realm, your rules:** Name who may enter. Draw the world’s edge. Switch survival and creative.

**Also new:**

- Chutes pass a stack a second from chest to chest. A Sorter keeps only what the chest before it holds.
- The Detector watches one block and hums when it changes.
- Water drinks a Blastcharge’s burst, and a burst throws a charge it touches. In your own worlds, /rules blasts off stops it.
- Tie your herd to a fence post. A pen one block high holds them.
- After a long storm the puddles stay a while.
- The Tale Entire: a deed for every page.
- Cairns fly a pennon in their colour, their band woven in it.
- Waterfalls spill off the Sky Islands and vanish into mist.
- On High, clouds cast their shadows across the land.
- No more sky through the middle of a tree’s crown.
- Torches stand on slabs. Slabs and stairs in Birch, Pine, Jungle, Stone, Granite, Chalkstone, Greystone, Slate, Basalt, Snow Brick, Terracotta and Skystone.
- Invite links carry a mark only you can give.
- Rest with the others from where you stand. The list shows who is away.
- A compass at home leads to your Bedroll or Homefire.
- New commands: /machines, /allow, /edge, /play, and /summon in single player.
- A frame counter any phone can switch on, in Settings.

## The thrum moves

A **Heaver** on the thrum heaves the line of blocks before its face one step, up to twelve; a **Hauler** heaves its block and hauls it home when the thrum goes. A **Chute** passes a stack a second from the chest at its back to the chest before it while the thrum reaches it, and a **Sorter** lets through only the kinds the chest before it already holds. A **Detector** watches the block before its eye and hums for a moment when it changes.

Nothing is made or lost: a move is all or nothing. Chests, claim stones and anything with items in it never move. `/machines` shows how hard a world’s machines are working.

## The Blastcharge

Light a **Blastcharge** with the thrum or a Flint and it bursts four seconds later. In the Riven Lands it breaks blocks only inside its placer’s own claim. In your own worlds it breaks what it reaches, unless you turn Blasts off with `/rules blasts off`. Water beside it drinks the blast, and a burst throws a charge it touches.

## Herds

Feed a cow wheat, a pig carrots or potatoes, a chicken seeds. Two fed animals of a kind bring a young one, which follows its herd and grows up. Lead them on a **Tether**, tie them to a fence post, and a pen one block high holds them.

## Hail and sandstorms

Hail hammers the plains in white streaks and bounces off the ground. Sandstorms rise over the desert, an ochre haze that dims the sun. After a long storm the puddles stay a while. In single player, `/weather hail` or `/weather sandstorm` brings one.

## The Heart

Isembard’s Shadow carries the last four Torn Pages, **XXI to XXIV**. Break it and a page falls; each night it comes again, it carries the next. Gather all twenty-four for **The Tale Entire**.

## Clocks and notes

A **Hearth Clock** keeps the hours on a mantel or a wall; a **Vael Dial** turns once a day, the sun at its top at noon. A **notepad** holds a note anyone can read and only you can write.

## Your Realm, your rules

A Realm’s keeper names who may enter (`/allow`), draws the world’s edge (`/edge`) and switches between survival and creative (`/play`).
