This is a continental map providing a glance at Erseria's four civilizations and eight Absolute Demon Realms. Colossia sits in the center, with Nivera to the north, Sardia to the west, Cardena and Ignas to the east, and Silvana and Morvana to the south. Marenos surrounds the outer sea. Cities, roads, ports, and ruins are also marked, making it easy to understand travel routes and power dynamics.

エルセリアの四大文明圏と八大絶対魔境を一望できる大陸地図だ。中央にはコロシアがあり、北にニヴェラ、西にサルディア、東にカルデナとイグナス、南にシルヴァナとモルバナが広がる。外海はマレノスに囲まれ、都市、街道、港、遺跡も記されているため、旅の経路や勢力関係を理解する際にも役立つ。

This map presents the four civilizations and eight Absolute Demon Realms of Erseria in a single view. Colossia occupies the center, with Nivera in the north, Sardia in the west, Cardena and Ignas in the east, and Silvana and Morvana across the south. Marenos surrounds the continent as a vast oceanic realm. Major cities, roads, ports, ruins, borders, and routes are marked as well, so the map is useful not only for geography but also for understanding travel, trade, political influence, and the dangers separating each region.

This is the grade chart used to compare the strength of humans and monsters in Erseria. Humans become stronger as they move from Grade 10 to Grade 1, and monsters become more dangerous as they rise from Rank F to Rank X. Entities on the same line are grouped into similar power levels for quick comparison. Grade 0 is not the next stage of growth, but signifies a divine being that cannot be measured by standard criteria.

エルセリアで人間とモンスターの強さを比べる際に使われる等級表だ。人間は10等級から1等級へ進むほど強くなり、モンスターはF級からX級へ上がるほど危険になる。同じ段はおおよそ近い戦力として並べられているため、力の差をすぐに確認できる。0等級は成長の次段階ではなく、通常の基準では測れない神格存在を示している。

🇺🇸 English .

This chart is the standard reference for comparing human strength and monster danger in Erseria. Humans grow stronger as their grade falls from Grade 10 toward Grade 1, while monsters become more dangerous as their rank rises from F to X. Entries placed on the same row represent roughly comparable levels of power, making the overall balance easy to understand at a glance. Grade 0 is not simply the next stage of human growth. It stands outside the ordinary system and refers to a divine being whose power cannot be measured by the same standards.

This is a comprehensive encyclopedia of the environments and representative monsters of the eight Absolute Demon Realms by region. Environments vary greatly—deep sea, ice fields, deserts, giant-beast zones, jungles, mountain ranges, volcanoes, and swamps—so monster ecology and combat styles are distinctly divided by region. Each card displays four representative species and a danger range of D–X, with the final name representing the X-rank dominant species that exists as the sole ruler of that realm.

🇯🇵 Japanese .

八大絶対魔境の環境と代表モンスターを地域別にまとめた総合図鑑だ。深海、氷原、砂漠、巨獣地帯、密林、山脈、火山、湿地など環境が大きく異なるため、地域ごとに魔物の生態や戦い方もはっきり分かれている。各カードには代表種四体と危険範囲D～Xが記され、最後の名前は、その魔境に一体だけ存在するX級支配種を示している。

🇺🇸 English .

This bestiary introduces the environments and signature monsters of all eight Absolute Demon Realms. Each region has a distinct climate and landscape, from abyssal seas and frozen plains to deserts, giant-beast territories, jungles, mountain ranges, volcanoes, and swamps. Those differences shape the creatures that live there, including their bodies, habits, and fighting styles. Every card lists four representative monsters and a threat range from D to X. The final name on each card is especially important, as it identifies the realm’s one and only X-rank dominant.

This is the highest-tier encyclopedia featuring the eight X-rank dominant species at the pinnacle of the eight Absolute Demon Realms. They are not just strong monsters, but beings that maintain the climate, ecosystem, and mana circulation of each realm. Each card records the name, alias, disaster type, and changes that will occur upon awakening. A continent-scale disaster can occur just by one of them moving or fully awakening, and even the strongest cannot guarantee a solo subjugation.

🇯🇵 Japanese .

八大絶対魔境の頂点に立つ八体のX級支配種を収録した最上位図鑑だ。彼らは単に強い魔物ではなく、各魔境の気候、生態系、魔力循環を維持する存在でもある。各カードには名前、異名、災害の種類、覚醒時に起こる変化が記されている。一体が移動したり完全に目覚めたりするだけで大陸規模の災害が起こり得るため、最強者でも単独討伐を断言できない。

🇺🇸 English .

This highest-level codex gathers the eight X-rank dominants that stand at the top of Erseria’s Absolute Demon Realms. They are not merely powerful monsters. Each one helps regulate the climate, ecosystem, and magical circulation of its territory. Every card records the ruler’s name, title, disaster type, and the changes expected if it awakens. Even a single dominant leaving its usual range can trigger a continent-scale crisis, and destroying one may damage the balance it once maintained. For that reason, even Erseria’s strongest individuals cannot guarantee a solo victory.
