Aurora Borealis

This is a shattered planet that is tidally locked, existing in a state of perpetual extreme day on one side and extreme night on the other. Only the continent of Aestra, situated in the twilight zone, enjoys the normal alternation of day and night. Its life-supporting natural environment has given rise to various forms of life. Although this place is merely a gap in the world, there are still many distinct places within the Aestra continent, such as the large floating island 'Sky Blue Island', the desolate sea desert in the west, the Astra Plains in the center, the Valley of the Sky in the east, and the Snowy Mountains in the north.

Overview of the Aestra Continent

✦ Sky Blue Island·White Night Castle

Sky Blue Island is a massive floating island on the Astra Plains, where the large floating city 'White Night Castle', the center of Astra civilization, is located. It is divided into upper and lower layers. The lower layer, inhabited by commoners and slaves, has a distinct social class structure, while the upper layer comprises the Senate formed by governors and noblemen and the temples of priests, establishing a system of separation of powers. The noble, elegant, and magnificent world of the upper layer is completely different from the lower one. This sky city, endowed with highly advanced magic and classical culture, boasts the most advanced military and civilization. The lord of the floating city 'White Night Castle' possesses all supreme powers and believes himself to be the protector of all civilizations in Aestra, remaining vigilant against the emerging Enlightenment Federation.

✦ Below Sky Blue Island·Shadow Town

Shadow Town is a ground town located beneath Sky Blue Island, serving as the entrance to White Night Castle and one of the most convenient places for transportation in Astra. Just as a shadow is cast by light, this place is not bound by the laws of White Night Castle and is filled with chaotic vibes under the influence of multiple forces. Shadow Town maintains a neutral stance towards all forces, allowing anyone to take what they need; it stands as the actual commercial center of Astra. Initially managed by the security team of White Night Castle, it later developed into an actual self-governing area controlled by local underground forces and guilds. The scenes in Shadow Town are always shrouded in dark, cloudy weather and interwoven streets, where the seemingly tranquil streets hide undercurrents.

✦ Red Oil Desert

Located in the western part of Astra, this great desert was where the pioneering organization called the 'Red Oil Wrench' discovered and repaired a monument, naming it 'Landwalker' and establishing a ground camp based on it. Subsequently, people tacitly acknowledged this place as the territory of the Red Oil Wrench, referring to it as the 'Red Oil Desert'. As the wilderness where the pioneers live, the Red Oil Desert leaves the deepest impression with its boundless yellow sands and eclectic wasteland-style structures.

✦ Canaan Underground City·Enlightenment Federation

'Canaan City' is located underground in the Astra Plains and is the core component of the Enlightenment Federation. As the frontline against the Dark Ghosts, it cannot be as clean and bright as White Night Castle, with an overall design focusing on functional industrial style. The people of Enlightenment value high unity and efficiency above all, reflected in the architectural style that showcases a unique sense of strength characteristic of the legion. They promote universal education and implement a 'meritocracy' system that prioritizes individuals with capability. Different factions derived from White Night Castle have a starkly different social structure from White Night Castle itself.

✦ Valley of the Sky·Sky Clan

A tribe that is distant from other forces' disputes, they have their own cultural customs and fashion styles. They often wear hooded cloaks adorned with geometric patterns, pursuing a blend of tribal culture and technology. The Sky Clan is the most mysterious race in Aestra, gathering and living in the Valley of the Sky. They were annihilated by the world enemy, the Dark Ghosts, during a historical event known as the Dark Tide Crisis, leaving only desolate land behind today.

✦ Spine of the World·Northern Region

In the northern part of the Aestra continent lies a snowy mountain range known as the 'Spine of the World.' The Light Spirits living here refer to the land where they have taken root as the Northern Region and call themselves the People of the North. The Northern Camp is a watchtower removed from all disputes, blessed by mountains and lighthouses. Under the protection of the Northern Queen, the Light Spirits are able to live a peaceful and comfortable life.

✦ Foreign Lands

The resilient Light Spirits have left traces of their civilization in many other locations in the Aestra continent, each with unique local customs and cultures distinct from the aforementioned areas. It is said that further beyond the Aestra continent to the east lies the Dragon Continent, which harbors another culture... the veil of mystery awaits to be unveiled by future navigators.

Introduction of Races

✦ Dark Ghosts

Dark Ghosts are ominous beings that utilize an unintelligible eclipse language, committing slaughter and destruction with unknown purposes. Since historical records began, Dark Ghosts have stood as a public enemy. Ruthless and devoid of rationality, they relentlessly seek the will of the so-called 'Mother'. They are part of a conspiracy organization called Eclipse, which claims to enable its members to realize ambitions and dreams, and uses this as leverage to absorb rebels from various factions and races attempting to launch another attack against Aestra.

✦ Light Spirits

The abilities of Light Spirits contrast sharply with those of the Sky Clan. They can harness light energy as their source of power, employing various light energy techniques to combat Dark Ghosts, but cannot perceive the trajectory of light energy's operation.

✦ Sky Clan

Sky Clan members are inherently delicate and cannot engage in combat. However, they possess a unique talent known as 'Sensing Ability', allowing them to perceive the trajectories of light, comprehend the thoughts of their companions, and guide Light Spirits to fight more effectively. Additionally, they have powerful battle companions—Golems. Golems can serve as transportation and weapons, and can even possess self-awareness, communicate with, and be piloted by them.

Currently, Light Spirits are divided into several major factions, including White Night Castle, Enlightenment Federation, Red Oil Wrench, Shadow Town, the Truth Society, and the Northern Region. Of course, aside from these major factions, there are also those without any affiliation, wandering in the margins of factions. Many small groups, unidentified organizations, and residents of lost ruins are among them. Due to geographical remoteness, or to maintain their independence, or due to their inherent nature of being nomadic, they do not belong to any faction within Aestra civilization and are collectively referred to as the Unaffiliated.

✦ Truth Society

An ancient secret society with members hidden within various factions in Aestra. They believe that the publicly available history of White Night Castle is false and are dedicated to unearthing the buried truth.
