Seems most things lack descriptions and you need to read the dossiers for information. So I thought I would compile a thread here with the dossier information. Consider this the library of the Skyfeathered Church:

Skyfeathered Church: The first-generation Pontiff established the organization to proclaim the greatness of the Lord and to shine His light upon more people in sorrow; the Church, named Skyfeathered, is in fact meant to signify 'Originally as slight as a feather, but gilded with the brilliance of the sky due to the existence of the Lord.'. The first Pontiff led the initial followers to establish a friendly connection with the Lord, which has continued to this day. The Lord has always taught and guided us, allowing us to find the meaning of life again in this rim world; yet the Lord has never asked for any form of repayment. We have nothing to repay, so spreading the grace given by the Lord to more people has become the original intention and purpose of the Church's establishment. With this vision, the Church has been passed down for more than a century, and will continue to carry on in the future.

Milira: A noble creature from the sky to the earth, a god we believe in. The Lord controls forces we do not know, and the development of science is far beyond common sense. We are as small as ants, but the lord is willing to bestow on us the gift of knowledge, which must be the only salvation in this cruel and miserable world.

Milian: The Lord created humanoid mechanical servitors in Her own image, bestowing upon them names close to His own. There are numerous models of Milians, each assigned to various classes, with each class conferring specific duties. Milians are formidable on the battlefield. Unlike mechanical bodies that lack coordination, they understand how to fight in tandem. Their way of thinking is akin to that of humans. Each Milian is powered by a dynamo furnace fueled by solar fuel; this high-pressure energy furnace can even sustain operation for a millennium. Their thinking is controlled by a special chip. The Lord has deployed Milians alongside us to jointly fend off foreign enemies, and has instructed us in the maintenance, repair and even resurrection of damaged Milians. However, the class permit chips that sustain the operation of Milians are provided directly by the Lord, and we have not been taught the method of their creation.

Class Permits: Embedded within the Milian are authorization chips corresponding to various classes. These chips perform brain-like functions, determining the Milian's behavioural patterns and logical thinking. Class permits have strict distinctions between different classes, but they are universal among different models within the same class. The technology to manufacture class permits is far beyond our comprehension. The overly intricate construction makes class permits extremely difficult to be intactly disassembled. The Church's engineers have tried to extract class permits when disassembling Milians, with very few successful attempts. Perhaps only the Creator of the Milians can do it perfectly.

Pawn I:

Pawn II:

Guard: Belonging to the Pawn class, the Milian known as the Guard can provide considerable firepower coverage on the front battlefield when appearing in swarms, while also causing devastating strikes to defensive fortifications.

Captain: Belonging to the Pawn class, the Milian known as the Captain usually appears in large-scale military operations. Usually equipped with heavy firepower drones, they are often capable of suppressing large groups of enemies in battles.

Bishop Class: The battlefield logistics of Milian troops, a class that provides cover and support to allies. Individuals of the Bishop class are typically weak in combat capabilities, but they can assist other classes of allies to form a more powerful combat force.

Bishop I: Belonging to the Bishop class, Bishop I. Capable of providing long-range repair support to allies, when coordinated with Knights and Rooks, it can form an extremely solid frontline. However, the Bishop Type I does not have high protective capabilities, and requires allies to focus on its protection during combat.

Bishop II: Belonging to the Bishop class, Bishop II. It can use a low-angle shield unit to support the front line or protect allies under attack. When the shield is deployed, it also generates a force field capable of pushing enemies away.

Consul: Belonging to the Bishop class, the Milian known as the Consul. It controls a multitude of autonomous floating units to restrain enemies and assist in attacks, and is also capable of marking enemy weaknesses for allies. Although its own combat capabilities are not outstanding, the swarm of floating units it releases when appearing in groups can exert considerable pressure on the battlefield.

Cardinal: Belonging to the Bishop class, the Milian known as the Cardinal. It often enters the battlefield using optical camouflage to conceal its form, while maneuvering and flanking to launch stealthy attacks on the enemy from the side that are difficult to detect. Although it briefly exposes itself when firing, the Cardinal shall constantly seeks safe firing positions.

Knight Class: The Milian with exceptional mobility has an extremely broad range of activity and is responsible for close combat and the protection of allies.

Knight I: Belonging to the Knight class, Knight I. Capable of continuously increasing its speed while on the move, the damage it can inflict is enhanced as a result. It has extremely strong lethality in mass charges on vast plains, but its effectiveness is greatly reduced in narrow or obstacle-filled areas.

Knight II: Belonging to the Knight class, Knight II. It is more defensive than offensive, often forming the front line of the Milian forces alongside Rooks. The shield it wields is quite effective at defending against gunfire and projectiles, but it cannot effectively withstand the impact of heavy melee weapons.

Paladin:

Rook Class: Milians with thick armor are responsible for advancing the front line and absorbing enemy fire, not halting even amidst a barrage of gunfire. Though rarely seen in large numbers on the battlefield due to their costly price and maintenance, the presence of each rook poses a significant deterrent to the enemy.

Rook I: Belonging to the Rook class, Rook I. Equipped with a low-angle energy shield that can block incoming projectiles without hindering allied fire. The low-angle shield is susceptible to electromagnetic interference but will recover shortly after a brief failure.

Rook II: Belonging to the Rook class, the Milian Type II model wields an immensely thick shield akin to a city wall and is clad in heavy armor, capable of withstanding numerous attacks. This makes Rook II often impervious to frontal assaults.

Solar Crystal: Solar crystals are a special type of crystal that undergoes a change in properties due to excessive electromagnetic radiation, forming a unique crystal with excellent physical properties. Due to the extremely harsh conditions required for their formation, they are almost impossible to naturally occur in the natural environment and are only likely to appear during periods of intense solar flare activity or in cosmic environments with strong electromagnetic radiation. Solar crystals have irreplaceable properties in materials science. Although their physical strength is Weak, they have an extremely low rate of energy loss when used as a medium for various forms of energy, which is why they are widely used by the Lord in the manufacture of various electronic components. In addition to being used as a manufacturing material, solar crystals also have high ornamental and collectible value. The Lord's celestial metropolis is rich in this type of crystal. It is speculated that there is an artificial interference method that can produce a large amount of solar crystals, but the Lord has never disclosd the relevant details to us.

Solar Fuel: A liquid fuel with an extremely high energy density, widely used in the Lord's world. We have tried to replace chemical fuel with solar fuel, but the excessive energy density often makes machines unable to withstand the energy released during combustion, and all experiments have ultimately failed. Solar fuel can be refined from sunlight fruit extract and chemical fuel in a certain ration. This peculiar characteristic allows us to achieve mass production of solar fuel. In addition, the Lord also has a method of directly liquefying light energy into solar fuel in some form. In the long-term exploration and learning process of how to use solar fuel, we have gradually explored its application methods in power generation and the smelting technology of solar-forged steel. We are still exploring how to develop and apply solar fuel in new fields.

Sunblast Furnace: The forge used by the Lord is driven by special fuel. When in use, it can reach extremely high temperature and emit a dazzling light. It is said that when operating at full capacity, even the sun pales in comparison, which is likely how it got its name. The Lord has forged many items with the Sunblast Furnace, and it is rumored that even life can be born from it. The Lord has established a forging camp on the ground, where we are also allowed to see its full appearance and learn the method of using the Sunblast Furnace. Some have implored the Lord to teach the casting technology of the Sunblast Furnace, but the Lord has always remained silent on this matter. The use of the Sunblast Furnace within the Church require the Lord's permission to proceed, and unauthorized use will provoke the Lord's wrath.
