What the Mod Adds

Box of Infinite Books

A craftable block that dispenses Written Books. Each book is tied to a specific dimension — throw it into a Nether Portal to open a portal to that dimension.

Crafting: Bookshelf surrounded by books (see recipe)

Behaviour:

• Right-click — gives you a Written Book with a randomly generated title. The title is deterministic based on the block's position, so the same block always gives the same book.
• Right-click with an Echo Shard — binds the box, locking in its current seed permanently. A bound box glows. When broken, a bound box drops as a glowing item that remembers its seed, so you can re-place it anywhere and still get the same books.
• An unbound box dropped from breaking carries no data and will generate books based on wherever it is re-placed.

Infinity Portal

A converted Nether Portal that leads to a custom dimension. Each portal has a unique color matching its destination.

How to create one:

1. Build a standard Nether Portal and light it.
2. Write or obtain a Written Book.
3. Throw the book into the portal (drop it while standing inside, or toss it through).
4. The portal frame converts — the blocks turn into an Infinity Portal in a color unique to that dimension.

Redirecting a portal: Throw a different Written Book into an existing Infinity Portal to redirect it to a new dimension. The portal color will update to match the new destination.

Return portals: The first time you travel through an Infinity Portal, a return portal is automatically generated near the spawn point of the destination dimension. Step through it to come back.

Getting Specific Dimensions

There are three ways a book can target a dimension:

1. Named Dimensions (Exact Title Match)

If a Written Book's title exactly matches one of the names below (case-insensitive), it will always go to that specific hand-crafted dimension. Write the title yourself using a Book and Quill, sign it, then throw it into a portal.

Title	What it is
ancient	Deepslate/tuff/moss flat world
ant	White concrete floor (ant simulation placeholder)
cave	Dense stone with 3D-carved hollow voids
checkers	Black and white checkerboard floor (4×4 squares)
chess	Black and white checkerboard floor (4×4 squares)
clubs	Black and white checkerboard floor (4×4 squares)
colors	Four-quadrant floor: blue, red, green, yellow
dark	Stone below, obsidian surface
farm	Single bedrock floor with a normal day/night cycle — ideal for building farms. Pillager outposts spawn naturally for raid farms. Note: mobs can spawn on bedrock in darkness, so light up your build areas
flat	Standard grass flat world
floating	Circular grass islands floating at y=80, repeating every 32 blocks
gallery	Infinite bookshelf rooms (8×8 repeating) connected by small passages
grid	Stone pillars on a 4-block grid, open void between
holes	Flat world with circular holes punched through the floor every 48 blocks
inverted	Stone ceiling overhead, open void below
library	Infinite bookshelf rooms (8×8 repeating) connected by small passages
llama	Stone below, lime carpet surface
message	Nearly empty — one bedrock block at origin
museum	Infinite bookshelf rooms (8×8 repeating) connected by small passages
patterns	Bitcount-pattern black and white concrete floor
skygrid	Sparse grid of single blocks floating in the void
slime	Solid slime blocks from bedrock to y=64
sponge	Menger sponge fractal in sponge blocks, repeating every 27 blocks
underground	Dense stone with 3D-carved hollow voids
void	Single bedrock block at origin, otherwise empty
wall	Stone pillars on a 4-block grid, open void between

Tip: Titles are matched after trimming whitespace and converting to lowercase, so Library, LIBRARY, and library all go to the same place.

2. Box of Infinite Books (Generated Books)

Books dispensed by the Box of Infinite Books store the dimension ID directly in their pages — 16 pages, each containing 2 hex characters, which together form a 32-character ID. It is the page content that determines the destination, not the title. The title is just a human-readable label; renaming the book would not change where the portal goes.

You don't need to do anything special with these books; just throw them in a portal.

---

3. Hand-Written Books (Book and Quill)

Sign a Book and Quill and throw it into a portal. The mod checks the title first:

• If the title exactly matches a named dimension (e.g. the title is just library and nothing else) → goes to that easter-egg dimension.
• Otherwise → the page contents are hashed to produce the dimension ID. The title is ignored entirely.

This means for any book that isn't a named dimension:

• Whatever you write on the pages determines the dimension, regardless of the title.
• Two books with different titles but identical page content go to the same dimension.
• The same page content always opens the same portal to the same dimension, across any world or server.
• The resulting dimension is one of 18 procedurally generated terrain styles (see below).

Example: A book whose pages say the hollow mountain will always go to the same procedural dimension no matter what its title is, or who throws it.

Procedural Dimension Terrain Styles

Procedural dimensions (those reached by hashed titles or Box books) use one of 18 terrain styles, chosen deterministically from the dimension's seed:

Style	Description
Flat	Bedrock + stone + grass surface at y=64
Hills	Gently rolling terrain, y=48–80
Mountains	Tall noise-based peaks, y=40–140
Ocean	Water-filled basin, sea floor at y=30
Floating	Disconnected stone islands at y=80
Void	Bedrock floor only, otherwise empty
Cave	Mostly solid stone with ellipsoid-carved hollow pockets
Desert	Flat sandstone and sand plains
Mushroom	Flat mycelium surface
Inverted	Stone ceiling slab, open void below
Pillars	Tall narrow spires of varied height, separated by void
Archipelago	Ocean basin with scattered islands above sea level
Canyon	Flat plateau with deep noise-carved chasms
Cavern	Dense solid mass with large 3D hollowed voids
Mesa	High plateau (y=100) with banded strata and canyon carving
Lava Sea	Variable terrain with lava fill at y≤31
Frozen	Ocean floor terrain with solid packed-ice fill above
Amplified	Extreme mountains — same shape as Mountains but ×3 amplitude

All procedural dimensions use a palette of blocks derived from the seed, so the exact blocks used will vary between dimensions even within the same style.

Portal Colors

Each Infinity Portal displays one of 9 colors based on its destination dimension. The color is deterministic — the same dimension always gets the same color:

• Arcane Pink
• Crimson
• Gold
• Infernal Orange
• Silver
• Soul Blue
• Toxic Green
• Void Black
• Void Teal

Notes

• Procedural dimensions are saved to the world and persist across restarts — you will always return to the same generated terrain.
• Named dimensions are always available and do not need to be "discovered" first.
• The Nether Portal itself is unaffected — only a thrown Written Book triggers the conversion. Walking through a normal Nether Portal works as usual.
• Return portals are placed near world spawn (x=8, z=8) in the destination dimension. On void or floating-island dimensions where there is no ground, a small stone platform is generated automatically.
