# Scarcity and the Cap

The economy has one hard rule underneath everything: **nothing is infinite**.

## A fixed world

Every material in the world has a **bound**, set deliberately and written down. There is no faucet that quietly tops it back up. The game shows you how much of each thing is left, live, and from level 5 you get an observatory that shows you the whole picture at once.

The bound comes in two shapes, and it is worth knowing which one you are up against:

- **A ceiling.** Seven materials are **renewable**: they come back. What holds them is not a pool but a live count of every unit the world is holding **right now**, against a ceiling. While the world sits at that ceiling **nobody is getting any**, however long they play, until some of it is spent or crafted away.
- **A pool.** Four materials still sit in the ground in a fixed amount, zone by zone. Gather it, kill for it, craft it, spend it, and the total only ever goes down. When a pool reaches zero that material is gone from that zone for good.

Here is the whole world:

| Material | The bound |
|---|---|
| **Straw** | renewable, **ceiling 68,000** held at once |
| **Sap** | renewable, **ceiling 60,000** |
| **Hide** | renewable, **ceiling 57,000** |
| **Water** | renewable, **ceiling 42,000** |
| **Scrap** | renewable, **ceiling 39,000** |
| **Horse shit** | renewable, **ceiling 35,000**. No node gives it; see [how you earn it](/gluebook/gluniverse-horse-shit) |
| **Bone** | renewable, **ceiling 9,000**, everything the Ocean refines included |
| Frozen sap | a pool, 12,000, all of it on Knacker's Pass |
| Fishbone | a pool, 4,000, all of it in [the Ocean](/gluebook/gluniverse-ocean) |
| Iron fittings | a pool, 3,800, split across the seven grounds that drop it |
| Keystone | a pool, 1,500, all of it on Knacker's Pass |

## What changed on 10 August 2026, and why

Every material above the line used to be a pool. By the morning of 10 August the world had genuinely run out of ground: sap died at 04:31 that day, straw and water in the two days before it. Players were pulling around 28,000 units a day out of a world that held roughly 330,000, ever.

Emptying was the symptom. The cause was that a supply which only ever shrinks makes **holding** the winning move, so nothing traded and nothing got built. The five common materials were reclassed to renewable that day, at **exactly the totals their pools already held**, so the change added no supply at all. It only changed what happens when you spend.

A ceiling counts what is **held**, not what has ever existed: material bound inside something you crafted is invisible to it. So **crafting is what reopens the world**. Fire three shit into a brick and the world's shit count drops by three and somebody's stable can make three more.

Everything a bone touches is now everyone else's headroom: the [throw](/gluebook/gluniverse-throwing) shatters one with every human cast, every charm [fuse](/gluebook/the-item-catalog) eats one as a catalyst, and six of the ten charms price their craft in it.

## New ground is the only way a pool grows

The four pools grow one way only: a **brand new zone** arrives carrying its own pool, announced as content and visible in the supply figures from day one. No existing pool is ever edited, and nothing tops up what is already in the ground. Knacker's Pass is the most recent one, and it brought 12,000 frozen sap and 6,000 water of its own.

[Land](/gluebook/gluniverse-new-land) is the one thing that grows on a different rule, and it is not a material.

One deliberate exception, small and counted: the [Magic Tree](/gluebook/gluniverse-magic-tree) mints bricks, a crafted good, doubling what players feed it, hard capped per player per day and audited to the unit. Raw materials have no faucet, period.

## The relics got their bound

**Iron fittings** and **keystone**, the two relics the [big plots](/gluebook/gluniverse-the-field) ask for, were the last things in the world with no supply bound at all. They dropped, and nothing counted them. Since **6 August 2026** they have real pools like everything else: keystone all on Knacker's Pass, where the boss that drops it stands, and iron fittings split across the seven grounds whose creatures and chests actually produce them, weighted by how much each ground can really make.

Neither has a vendor floor, and that is on purpose rather than an oversight. A floor would mean every kill could be sold to a vendor for fresh gloo, which is the one change that would make the problem worse. The pool is the bound. The price stays absent, so relics trade player to player and on the Exchange, and nowhere else.

## The Hole, the one way material goes back

There is no faucet. There is, however, a **drain in reverse**, and it is a real place: **the Hole**, sitting at the centre of the crossroads in **Ashfell**. It opens to you at **level 6**, the tier where you first make things worth undoing.

Drop a **crafted** item into the Hole and half its recipe comes back to you, while the rest goes back to the world.

What that means depends on which of the two shapes the material is. For a **pool** material the units become **genuinely gatherable again**, at real nodes, in real zones, by anybody: a pool that had been worked down comes back up, and the next soul to walk that ground can pull what you gave back. For a **renewable** the world's half is simply destroyed, which is the same thing said differently: the ceiling's count drops and the room reopens for a node or a stable to fill.

Things worth knowing before you feed it:

- **It refills the emptiest ground first.** A unit does not remember where it was dug up, so returns go to whichever zone is furthest into its own pool. You are topping up the world's deepest shortage, not your own back yard.
- **It takes made things only.** Raw material has no recipe to split, so there is nothing to hand back and nothing to return. The Hole refuses it rather than eating it.
- **It refuses things the world also gives away.** Some items can be crafted **and** found: the boss-dropped charms and the frozen sword off [Lil Knacker](/gluebook/gluniverse-creatures), the waystone shard. The Hole cannot tell a made one from a found one, and paying out a bill of materials nobody ever spent would be a faucet. So it says no, and it says why. The item keeps every other use it has: wear it, sell it, trade it. **28 of the 35 things you can make still go in.**
- **At a full ceiling, the capped half is destroyed instead of refused.** It used to turn away any drop whose refund would push a renewable past its ceiling. No longer: the Hole takes the drop, and whatever **bone or horse shit** the world has no room to hold back is **destroyed** rather than handed to you, while the rest of the refund pays out as normal. The preview says exactly this before you drop, so nothing is destroyed unannounced. Drop the same item later, when the world has room, and it refunds in full.
- **It is one-way.** What goes in is gone from your bag. The Hole is how you put something back into the world, not a place to store it.

Nothing is ever created here. The Hole can only ever return what was genuinely taken out, and never one unit more, so the world's ceiling holds exactly as written above, no matter how much anyone feeds it.

## A watched currency

**gloo** is watched just as hard. It enters the world only through counted doors: the vendor floor, in exchange for real materials you gathered, the [Bank](/gluebook/gluniverse-bank) against real SOL, and a few bounded, audited cases like a winning [casino](/gluebook/gluniverse-casino) spin. Burns pull it back out: Exchange fees, racebook vig, the casino's edge. Every mint and every burn sits on an audit trail. Nobody can quietly print it. Not a player, not the market maker, not us.

## Rarity is real

Because supply is fixed and only shrinks, **rarity is a fact, not a label**. When something reads as rare on the Exchange, it is rare because the world is genuinely running out of it. That is the whole game: a small, finite world you share, and have to be smart about.

## The honest note

This is a game mechanic, not investment advice. Things are scarce because scarcity makes a world worth playing in, not because anything is promised to go up.
