About

1. What is Periodica? Periodica is a continent where elements live as beings with personalities and abilities based on their respective chemical properties. 2. How do the elements live? Elements in Periodica form regions with others who share similar properties. Each region reflects: • The chemical characteristics of those elements • The values and political attitudes formed from them ⸻ 3. Major Regions of Periodica (Overview) 🌪 Alkali Federation (West) • A region that is highly reactive, fast-acting, and emphasizes expansion • Possesses great power but also inherent instability 🌱 Union of Life (Central) • A community formed by elements of different groups cooperating • Values life, freedom, and the 'meaning of bonding' ⛰ Transition Metal Legion (Mountainous Region) • A region that emphasizes order, strength, and industry • The center of weapons and technology in Periodica ☣ Halogen Kingdom (East) • A region with strong reactivity and dominance • Maintains a tense relationship with surrounding nations ☁ Noble Gas Corps (Northern Sky) • An aerial city society composed of elements that rarely bond • Values neutrality, stability, and purity as the highest virtues ☢ Radiation Zone (Southern Wasteland) • A restricted area • Traces of an ancient war remain ——— The First Elemental War occurred 100 years ago between radioactive elements and ordinary elements. It was the largest war in Periodica's history, and as a result, radioactive elements were isolated in the Southern Wasteland. Iron fought on the front lines with his comrades during this war. As it was a large-scale conflict, many casualties occurred. Over time, Periodica regained its original daily life. ——— Transition Metal Mountains Core Characteristics • A region symbolizing strength, order, and accumulation • A fusion of natural terrain with military and industrial structures • The home base of the Transition Metal Legion • Geographical Features • Peaks are angular and sharp • Ore veins are exposed on the mountain surface • Various metallic components such as iron, copper, and nickel are mixed • Special Terrain • Magnetic Waterfall: Iron powder and metal fragments flow like water, stopping or flowing backward in mid-air • Metal Bedrock Ground: Metallic resonance occurs when walking • Structure Distribution • Natural caves are expanded into workshops, logistics routes, and fortresses • Near Ferros, the mountain itself is processed like a fortress wall • Numerous large-scale weapon manufacturing facilities and armories exist • Sky and Light • Iron-colored clouds often form • Strong reflected light occurs during the day • At night, it is constantly illuminated by furnace lights and electrical sparks • Environmental Atmosphere • The air is heavy and oppressive • Metallic resonance sounds echo like the wind • A culture that values discipline and results over emotion is formed Not all elements of the Transition Metal Legion are soldiers; there are noble metal families in charge of trade and diplomacy. Gold and Silver are representative examples. On one side of the mountain range is the 'Post-Transition Metal Village.' Elements like Aluminum, Gallium, and Tin, which have weaker characteristics than transition metals, live there.
