Astra is the city humanity built above Idyll after leaving Earth; Idyll is the continent the nine Aeons are said to have created, fed by the Veins under its soil. Below: every illustrated card of the game's World codex, then the murals, then the main story.
Aniimo opens on two worlds stacked on top of each other. Astra is the floating city humanity built after leaving Earth: a doomsday shelter that became a metropolis once it found the continent below. Idyll is that continent, wild, alive, and home to the creatures the whole game is named after. The Lore screen in the game explains both in short illustrated cards, and every one of them is reproduced below, word for word.
Read them in order and the game's systems stop being abstractions: the Veins under the ground are why Branches, Blooms, Lumin Amber and the Prismana Flow exist; Twine is the bond that makes a Pathfinder; the ruined Ancient Idyll civilisation and its Mechina are what the Sanctum dungeons are about. The story chapters, the letters and diaries and the curios and legendary perfumes each get their own page.
The predecessor of Astra was a doomsday shelter carrying the seeds of Earth’s civilization. After a long journey, it discovered Idyll. Humans built the city of Astra floating above Idyll into a vibrant metropolis and began exploring the continent.
With the discovery of Crystal energy and Ancient Civilization ruins on Idyll, researchers developed Lumintech, powered by Crystals. This efficient and clean new energy technology completely solved Astra’s energy problems.
Aniimo help Astraeans explore Idyll, and young people long to have their own Aniimo companions. Many Aniimo have moved into Astra alongside their human guardians. In newly built districts, facilities and products serving Aniimo can be seen everywhere.
An educational and research institution founded by renowned scholar and explorer Oswen, dedicated to Aniimo research and Idyll expeditions.
Students and Aniimo study and train together under the Institute’s guidance, living and growing side by side.
Aniimology is dedicated to documenting Aniimo ecosystems, analyzing Aniimo biological profiles, building the Aniilog, sharing Aniimo knowledge with the public, and developing Aniimo facilities to help create an environment where humans and Aniimo can coexist harmoniously.
The Pathfinding Dept. conducts scientific research and field expeditions. Its members venture deep into uncharted natural landscapes, investigate mysterious ancient ruins, uncover the secrets of Idyll, and drive the Expedition ever onward toward the next coordinates.
The Battle Art Dept. was established to strengthen physical training and prepare for crises in the wild. Using Holo-simulation technology, it focuses on improving human-Aniimo combat coordination and cultivating exceptional battle skills.
The outpost prepared by Polaris Institute for the Expedition provides Pathfinders exploring Idyll with services such as level assessments, Research Console reports, rest and healing, resource supply, and convenient teleportation.
The Aniipod, developed by Polaris Institute, is a device capable of catching, equipping, and training Aniimo. Its interior uses spatial folding technology to provide a comfortable resting space for Aniimo.
A Lumintech device provided by Polaris Institute for its members. This smart information device integrates multiple applications.
It also features twining enhancement, skill casting, energy transmission, and more.
Bidding farewell to their lost Earth homeland, humanity discovered a brand-new world: the beautiful and vibrant continent of Idyll. Its scenery is picturesque, its life diverse, and wondrous creatures called Aniimo can be found in every corner.
Legend holds that nine Aeons together created Idyll, each guarding a different domain. Under their guidance, Idyllians and Aniimo live together in harmony.
Unlike Astra’s trendy bustle, this land retains its untouched natural character. Simple-hearted Idyllians live peacefully here, adapting to the land, building settlements, and developing their industries with the help of Aniimo.
The once-glorious Ancient Idyll Civilization now lies in ruins. Venture deep into Sanctum ruins scattered across the land to uncover the secrets of Mechina. What forgotten stories lie sealed behind this lost history?
A wondrous technology invented by the Ancient Idyllians under the guidance of the Prime Aeons. At its core are magical devices capable of channeling Vein energy. It is said that the original purpose of this technology was to repair damaged Veins.
The Sanctum ruins scattered across Idyll were built by the Ancient Idyllians to repair damaged Veins. Descend into the depths of a Sanctum and activate long-dormant Mechina to restore the flow of Vein energy.
The domain ruled by the Aeon Aeolus, where sea breezes carry the fragrance of Duskwhisper, ocean waves play the melody of the tide’s song, and dazzling gems are born from the dance of earth flames. It is a fertile land of green fields, sea isles, and warm earth.
The green plains beloved by the wind, where silver sands stitch together blue seas and green hills. Low-drifting clouds wander over the soft grasslands, and beneath the snowy foothills a sea of flowers paints the land with romantic color. A small perfumery village lies nestled within.
Known as "the place where flowers bloom in abundance," this village is famed for its flowers and perfumes. Once every decade, a grand celebration called the "Bloom Festival" is held here, during which the residents present their handmade perfumes and await the Guardians’ blessing.
Beneath Idyll lies an intricate network of Veins, like the pulse of the natural world itself. The Veins ceaselessly send the energy needed for all life to grow to the surface. Places rich in Vein energy are always brimming with life.
Where the Veins converge, Branches form. The Idyllians believe that the Aeons deliver vitality to the land through the Veins, and so they treat Branches with reverence. By touching a Branch with sincerity, one can listen to the heartbeat of the earth and feel the Aeons’ blessing.
Touching a Branch and receiving the Veins’ acceptance and protection helps Pathfinders move through Idyll. When Vein energy is strong, not only does it invigorate the body, but Aniimo living nearby will also gather and become active, triggering a Wild Surge.
Blooms form at the intersecting nodes of the Vein network. Through Blooms, one can teleport quickly between Vein nodes. Many Idyllian settlements are built around Blooms.
Long ago, Idyll underwent a violent vibration, and Vein energy scattered. Over the ages, this drifting energy condensed into radiant Lumin Amber and scattered across the land. Returning Lumin Amber to a Branch helps nurture the Veins.
When enough Lumin Amber has merged with a Branch, the surging Veins once again pour abundant vitality into the earth. The overflowing energy rises into the sky and forms the brilliant Prismana Flow, drawing out the rare Prismana Form Aniimo.
Aniimo is the collective name for the wondrous creatures living across Idyll. They come in a rich variety of forms and habits. Aniimo not only wield Elemental Energy but can also evolve to change their appearance and enhance their abilities.
Evolution is an important transformation on an Aniimo’s growth journey. It not only enhances their abilities but also changes their appearance. Some Aniimo, influenced by different factors during growth, can even branch into different individuals.
The same species of Aniimo may evolve into different Forms in different regions, weather, times of day, or other special environments in order to survive. There is also a rare Form that only appears in a Prismana environment.
A mysterious bond exists between humans and Aniimo, allowing hearts to connect and senses to be shared.
Pathfinders can observe and perceive the world through their Aniimo’s perspective.
Since the Ancient Idyll era, the few who could twine with Aniimo have been called Pathfinders. Polaris Institute enhances the stability of twining through training and technological devices, though the underlying reasons for twining remain to be studied.
The World tab also keeps pictures: two cave murals from the Helgon and Infergon legend, the four panels of the Century-Old Promise, and the two picture strips of Jenny and Johnny. The captions are the game's.
Helgon, Rookey, and Infergon are sitting in a circle chatting. Nearby, a Helmut and a Jawling are lying on the ground asleep, while another Jawling has its teeth sunk into a Helmut’s helmet... There is also a recorder using ancient script. Perhaps long, long ago, the Helmut and Jawling families shared a friendly and harmonious bond.
Long ago, the mountains of the Russet Highlands surged and boiled, and the earth trembled violently. The Aniimo clans that lived here faced catastrophe.
Then a Helmwhelp rushed to the summit and, enduring the searing agony that engulfed its body, swallowed a Flame Flower that bloomed brightly amid the raging inferno.
The mountains returned to peace, but the Helmwhelp’s body was scorched blood-red. From then on, it could breathe roaring flames, transforming into the legendary Infergon.
Tucker, who liked to bury himself in a corner and sing, and Ron, the boy who longed for the stars and distant places... two lonely souls, meeting, were no longer alone. Yet a hundred years can sometimes be too short, and sometimes very long. To say farewell is to never meet again.
