Glossary of Terms
1. 🟥 The Red Aurora
Fifty years ago, the creation of the Philosopher's Stone released a wave of Primordial Radiation across the globe. The phenomenon — called the Red Aurora — changed everything.
2. ⚗️ Primordial Radiation Effects
Ordinary (80%) — No reaction. Normal humans.
Affinity (20%) — Can manipulate specific alchemical ingredients.
Overload (15%) — Transmuted into monsters.
3. 🧪 The Seven Alchemical Ingredients
Each ingredient has physical, magical, and sensory properties. Resonants can wield them directly through touch.
Mercury (Hydrarch) – Volatility, transformation, magnetic collection.
Sulphur (Ignarch) – Fire, explosion, passion.
Salt (Crystarch) – Stability, defense, barriers.
Cinnabar (Rubarch) – Fusion of mercury + sulphur, rare and powerful.
Antimony (Noctarch) – Negation, stealth, silence.
Silver (Lunarch) – Healing, purity, light.
Gold (Aurelarch) – Amplification, perfection, leadership.
4. 💠 Affinity System and Resonants
Affinity determines which ingredients resonate with you. Most people have none. Rare individuals have 2–3. The legendary Heptabound (7 affinities) are almost mythical.
Resonants – Those who can resonate with alchemical ingredients. Trained, licensed, and deployed in missions.
5. 🎖️ Ranks
Rank is based on number of affinities and skill:
D (1 affinity)
C (1–2)
B (2–3)
A (3–4)
S (4–5)
SS (5–6)
SSS (7 — Heptabound)
6. 👹 The Transmuted
Humans whose bodies reacted too violently to the Red Aurora, becoming unstable monsters fused with ingredients. They drop alchemical materials upon death.
First Generation – Original monsters, ancient, near-godlike.
Second/Third Generation – Formed from exposure.
Emergents – People who transmute suddenly.
7. 🛡️ The Resonants (Profession)
Resonants are licensed alchemically-reactive individuals. They:
Hunt Transmuted
Harvest ingredients
Operate in zones of contamination
Are ranked and assigned missions by corporations
Common roles:
Collectors (Mercurials)
Healers (Silvers)
Vanguards (Sulphur/Gold)
Defenders (Sal)
Scouts/Assassins (Antimony)
8. 🏢 Megacorporations
Governments fell after the Aurora. Now the world is ruled by corporate power:
Prometheus Industries – Ruthless and efficient
Athanor Corporation – Knowledge above all
Leviathan Group – High-risk, high-reward
Solaris Collective – Cooperative idealists
Aegis Security – Defensive specialists
and much more.
9. ⚔️ Equipment & Combat
Combat uses:
Vials of ingredients
Special gloves to control contact
Layered clothing to avoid skin exposure
Tactics rely on:
Choosing right ingredient
Managing reactions
Avoiding overdose or cross-contamination
10. 📖 Glossary of Core Terms

💌 Author's Note
Look, reader — this is a narrative that will dive deep into magic systems, lore, and, of course, monsters. Brew a cup of coffee, pour yourself your favorite drink, and enjoy the journey with me.
Regarding the use of AI: I am a Brazilian writer with a solid command of English, though not a perfect one. I use AI to correct errors, find more suitable wording to improve readability, and expand my vocabulary. The only other way I use AI is for organization — such as creating reference sheets that help me manage and filter the worldbuilding I've developed (like this compendium). All creative and narrative work is done by me.
