In development · Working toward the first single-player demo
Make a home in a magical world
Beyond the city’s shelter, a crystal-rich wilderness waits. Manage up to 9 covens of 3 mages, send your covens exploring, and turn what they bring home into new possibilities. A resource becomes a spell. A spell changes a loadout. A better-prepared coven ventures out again.
The heart of Sapphire City
These are the systems taking shape in the current game. We’re refining the first demo, with more of the city to follow.
Choose your mages’ looks, pair major and minor affinities from nine magical paths, and invest in their training. Manage a guild of up to 9 covens of 3 mages, and build covens whose strengths support one another.
Gather resources with distinct aspects, combine them in researched patterns, and see how each ingredient changes the spell you are making.
Create and name spells, choose their colors, and equip your available slots. Mix damage, healing, shielding, and lingering effects to shape your approach.
Explore Spellwright, Runecarving, Summoning, and Enchanter. Research patterns and turn your materials into spells and equipment.
Watch your covens travel, battle, and gather automatically. Their loadout matters: healing responds to injuries, protection absorbs damage, and gear changes their strengths.
Manage the refined crystal currency behind casting, crafting, and expedition costs. Bring home resources, improve your equipment, and prepare for the next journey.
The first demo focuses on single-player play. Multiplayer and a larger town experience are future development, not currently available features.

Your foothold on Corundra
Sapphire City is more than a name. It is the last great shelter on a planet that has resisted every attempt to tame it. Beneath its crystal spire, your guild begins with modest rooms and ambitious plans.

Our narrated introduction follows Corundra’s history to your arrival. Illustrated in the same chibi art style as the game.
The chronicles of Corundra
A timeline of the major eras. Exact dates—and the origin of Sapphire City’s barrier—remain part of the world’s untold history.
Corundra’s crystals are a gift of nature. Their magic seeps into rivers, roots, creatures, and the wild places beyond civilization. Great wealth and great danger grow from the same ground.
After an age of mechanical invention, the crystalline Corundans learn to harness their planet’s deposits. The Awakening brings magitech: magical power shaped by practical craft.
Refined crystal becomes Dust. This portable source of power transforms industry and helps make passage between the stars possible. Other worlds grow dependent on Corundran fuel and expertise.
Ancient noble houses judge Corundans by their bodies’ color, clarity, and flaws. Other peoples are treated as lesser still. The ruling hierarchy closes doors that invention alone cannot open.
Resentment becomes rebellion. The Great Cleaving shakes the old order, but the ruling houses survive and those who challenge them are crushed.
Power is divided so no single house can hold it all: the Ledger controls money, the High Alchemist Guild controls Dust, and the Wayfinders control passage between the stars.
Corundra is still untamed. Failed settlements lie beyond Sapphire City, the planet’s only surviving great city. Its barrier can be maintained, but cannot be reproduced. The identity of its extraordinary maker is lost to history.
Your plans survive the journey; your shipment does not. Criminals take the tools and supplies sent ahead. A rented basement remains, and with it a foothold from which to build your guild’s future.
