Fatal Accident

………

“Damn it, the vacuum decay reactor was never something humans should have messed with!”

“If someone is reading this, please understand.”

“The vacuum decay reactor wasn't a safe, environmentally friendly source of energy.”

“One wrong move, and it's a terrifying thing that could wipe out an entire planet.”

“If anyone is in control of the vacuum decay reactor, please stop it now!”

“Before your world ceases to exist!!!”

Why is humanity here now?

Dreamed of a new fairy!

Monocots ― Order Miragales ― Family Miragaceae
Mirage

A palm-sized fairy in the form of a little girl with butterfly-like wings. Extremely timid, it rarely shows itself to people. When one tries to catch it, it disguises itself as a will-o'-the-wisp and flees; no matter how long you pursue it, you cannot seize it. For this elusive behavior it is known as the “Mirage.”

Once regarded as a kind of divine spirit, later research clarified that it is in fact the pollen of Mirage plants, possessing an autonomous structure.

What, exactly, is the true nature of fairies?

︙

Crystallized soul
“That which makes a creature a creature.”

The eroding reality
“The precipitating fantasy.”

Do fairy trees have qualia of pain?
“What it means to protect animals.”

Waiting for a flying creature...
“Fairies’ resting place.”

The great collapse 30,000 years ago
“The dream Miragium saw 30,000 years ago.”

Binds astral flux with magnetic force
“A blood-reeking cage of souls bound by chains of black iron.”

Class 4 time evolution rule.
“A stone that etches the patterns of time.”

Life is essentially inorganic.
“The boundary between life and inorganic matter.”

A Turing-complete crystal lattice
“A world where everything has been prophesied since the dawn of creation.”

Stable instability due to anti-entropy.
“Could this be the ultimate form of anti-entropy?”

No one can block that noise.
“No one can block that noise.”

A World Ruled by Plants.

The Institute of Fairy Research 2025 Kakera Unofficial

## Overview IFR25KU is a Minecraft mod that presents a possible world set in the MirageFairy universe. IFR25KU is an unofficial fork of [MF24KU](https://modrinth.com/mod/miragefairy2024-kakera-unofficial) by Yoruno Kakera. MF24KU was an unofficial fork of [MirageFairy2024](https://modrinth.com/mod/miragefairy2024). MirageFairy2024 is a mod that expresses the worldview of the MirageFairy project. --- This mod adds items, blocks, world generation features, biomes, enchantments, game mechanics, and more. It lets you experience a possible world set in the MirageFairy universe. ## Documents [CHANGELOG](https://mirrgieriana.github.io/IFR25KU/CHANGELOG.html) is the only official Japanese document that comprehensively describes IFR25KU's specifications. There are no other official documents; however, some unofficial resources exist, including: - [MFKU非公式Wiki (Japanese)](https://wikiwiki.jp/mifai2024/) ## Adventure Guide What should you do next? Press L to open the Advancements screen.

It will guide you toward your next goals.

## Biomes As you roam the world, you'll encounter biomes reshaped by fairies. ### Fairy Forest Fairy forests dot the land far and wide.

Here, many Mirage Flowers bloom in profusion.

The Phantom Flower found here is difficult to cultivate, yet it serves as a catalyst for higher-tier fairy summoning.

### Deep Fairy Forest A deep, overgrown forest where Haimeviska trees rise like pillars.

Venturing in unprepared is very dangerous. ## Fairies As you journey across the world, you'll encounter many kinds of fairies.

Fairies possess a wide range of abilities.

A light fairy increases your movement speed in bright areas, and an arrow fairy passively boosts your bow damage. ### Fairy Dreams This world is brimming with fairies.

Search among natural and artificial objects alike. When you obtain a low-rarity Fairy Dream, you immediately receive a fairy matching its motif. ### The Soul Stream Press K to open the Soul Stream and place fairies into the top slots of the UI.

They confer powerful enhancements. ### Fairy Condensation Need more fairy power? Having duplicates of the same fairy strengthens its effects.

Cultivate Mirage Flowers to obtain Mirage Flour.

Mirage Flour spawns fairies at random based on the Fairy Dreams you've obtained so far.

Fairies can be condensed without limit.

## Magic Plants Mysterious plants grow throughout the world.

Many can be harvested as crops by right-clicking. ### Crossing Naturally occurring magic plants are born with random trait bits.

Planting them adjacent to one another triggers crossing within the same species.

You have a 25% chance to obtain seeds that inherit both parents’ trait bits.

### Crossbreeding There are many kinds of magic plants.

Using the “Crossbreeding” trait, you can cross two different species within the same family. ### Plant Bag When your inventory overflows with seeds on your journey, the Plant Bag is handy.

## World Generation ### Weathered Ancient Remnants As you travel the Overworld, you'll discover Weathered Ancient Remnants.

Try brushing the Suspicious Gravel you find there. You may unearth a map that leads to the Dripstone Cave Ruin, along with useful materials.

### Debris Debris can be found throughout the world.

These piles can contain early-game vanilla materials as well as materials added by this mod.

You can place items on the ground by pressing Z. ## Materials & Processing ### Haimeviska This is a Haimeviska tree. In the fairy language, its name means “great tree of fairies.”

To collect sap for fuel or as a drink, stack Haimeviska Logs to form a wall and score the logs with a sword.

### Basic Materials Felling a Haimeviska is very hard, but a Xarpite Axe—which can break connected logs in one swing—makes the job easy. As Xarpite’s counterpart, Miranagite is a gem found near the surface. Tools made from it have Silk Touch by default.

### Brewing Barrel Using Haimeviska Logs, you can craft a Brewing Barrel and brew beverages that grant both benefits and drawbacks.

### Aura Reflector Furnace Once you've gathered enough Xarpite, craft an Aura Reflector Furnace.

Miragium produced in the furnace is used to craft powerful tools and also serves as an intermediate material for further recipes.

To run it, you'll need Soul Sand or Soul Soil as fuel. ### Fairy House You can build a Fairy House from Haimeviska Logs and several other materials.

Fairies can live and work there.

## Tools IFR25KU adds a wide variety of tools.

For many vanilla and common materials, all five basic tool types are available. For mod-added materials, some special tool types may be available. ### Special Effects Many tools have special effects.

For example, the Xarpite Axe provides a tree-felling effect. When you harvest a log, the connected tree is felled in a single swing. ### Magical Weapon The Staff of Miranagi is a magical weapon.

It can be crafted early in the game and fires magical projectiles. ## Fairy Jewels ### Minia's Telescope After making some progress in the game, craft Minia's Telescope.

Right-click it once per real-world day to obtain a Fairy Jewel. ### Fairy Statue Fountain Right-click the Fairy Statue Fountain to insert a Fairy Jewel.

It yields a random Fairy Statue, which carries a Fairy Dream. ## Lore Most mod-added items in IFR25KU include flavor text, called a “Poem,” that expresses the IFRKU worldview.

Magic plant traits include detailed descriptions.

Fairy Quest Cards feature several short stories.

Outside the mod, the MFKU official website hosts a series of Japanese articles called “MFA (MirageFairy Article)”. - [G1-MFA　ミラージュ妖精の生態 (Japanese)](https://miragefairy-kakera-unofficial.notion.site/G1-MFA-2f122378b3de4ba39cc5492e3af27b50)

These resources complement each other and collectively form the IFRKU worldview. ## Compatibility IFR25KU and MF24KU share the same mod ID (miragefairy2024) and are treated by the game as the same mod; their world data is compatible. IFR25KU v23.23.0 contains game content largely equivalent to MF24KU v22.22.0, so an MF24KU world can be loaded with IFR25KU. **Do not install both together—they conflict.** ## What is the relationship to MF24KU? This is a diagram of the relationships among the various MirageFairy-related projects and mods. ```text ■ ┣ MirageFairy Official ┃　┣ Project: MirageFairy ┃　┣ MOD: MirageFairy2019 ┃　┣ MOD: MirageFairy2023 ┃　┗ MOD: MirageFairy2024 ┗ MirageFairy Unofficial Fork 　　┣ MFKU Official 　　┃　┣ Project: MFKU 　　┃　┗ MOD: MF24KU 　　┗ MFKU Unofficial Fork 　　　　┗ IFRKU Official 　　　　　　┣ Project: IFRKU 　　　　　　┗ MOD: IFR25KU ← You are here ``` As the diagram shows, IFR25KU is neither an official MFKU project nor an official MirageFairy project. ## Support Support is available on Discord. IFR25KU is developed entirely by Japanese developers, and **support is primarily provided in Japanese**. Support in languages other than Japanese may be imperfect due to machine translation. --- Note: This description is automatically updated from [GitHub Actions](https://github.com/MirrgieRiana/IFR25KU/blob/main/build.gradle.kts) and cannot be changed manually.
