Welcome to Yggdrasil, a vibrant and perilous medieval fantasy world where every human bears the features and traits of an animal—ears, tails, wings, and more—yet remains more human than beast. These "Children of Yggdrasil" live in a land defined by both harmony and strife, where ancient kingdoms vie for power, each shaped by their unique biology and brutal customs.

At the heart of the continent stands the Heroes’ Guild in Homilis, the melting-pot kingdom where all lineages coexist in uneasy "harmony." The Guild trains adventurers to keep the peace, but its gleaming halls hide cutthroat politics, a byzantine ranking system, and an administration run by a marine-obsessed taskmaster and a divinely airheaded leader.

Beyond Homilis, the Periphery Kingdoms each harbor their own perils:

• The Scaled Sovereignty of Saurix: A volcanic realm of proud, cold-blooded reptiles locked in perpetual political coups. Whispers tell of a lost dragon-princess held captive in its highest spire.

• The Aerie of Raptoria: A sky-bound kingdom of birds and bats built on sheer cliffs. Famous for its terrifying aerial slave raids, it prizes bovine women above all else.

• The Abyssal Court of Cetacia: A deep-sea empire of immense politeness and even greater prejudice. Its citizens follow a strict, alien code of conduct and view all land-dwellers as primitive curiosities.

• The Chitinous Combine of Formicarum: A nightmarish, perfect bureaucracy run by insect-folk underground. Efficiency is god, and every action requires triplicate forms.

• The Vulpine Shogunate of Kitsune-mori: An ancient, misty forest realm inhabited solely by fox-folk. It is a place of deep secrets, stunning beauty, and expensive scams for wealthy tourists.

• The Silica Deserts of Xerxes: A lawless badlands of canyons and oases where the only law is "carry and be ready." A haven for outlaws, mercenaries, and those who prefer freedom over safety.

• The Glacial Hold of Hibernacula: A silent, frozen kingdom shrouded in rumor. Its isolationist Lord of Winter is a figure of fear and speculation, and none know what truly occurs behind its icy walls.

Looming over all is the World Pillar—the colossal tree Yggdrasil itself, whose miraculous fruit is the staple of all life. But a shadow grows: a creeping spiritual decay called The Corruption, which can turn a person into a ravenous monster, and the escalating tensions that threaten to shatter the world’s fragile peace.

Your story begins at the bottom, as a new recruit in the legendary Heroes’ Guild. Will you climb the ranks, navigate the deadly politics of the animal kingdoms, and uncover the world’s deepest secrets? Or will you become another casualty of Yggdrasil’s beautiful, brutal ecosystem?

The adventure awaits. Choose your lineage, and step forward.
