Honkai - Manifests in many ways that put the people of Earth under trial. They exist in many forms ranging from Honkai Beasts, Honkai Sickness, Herrschers, and emission of a new energy called Honkai Energy

Honkai Sickness - It is caused by exposure to Honkai Energy and early stages can immediately display signs of illness. It can be prevented through minimal contact with the ill and wearing protective clothing such as gloves and masks, but prolonged exposure will still cause people to contact Honkai Sickness.

Honkai Cascade is the condition of a patient's body having purple lines spread through his/her body. The majority who succumb to the sickness even with high levels of resistance will still die eventually

Valkyrie - This term will be mainly used to describe the fighters in the game, they were termed as such due to women having higher rates of developing Honkai Resistance than men. Males will be called Chevaliers. Despite them only existing in one organization, they'll still be used to determine the strength of allies and enemies

Stigmata - Otherwise known as Witch Mark or Cursed Mark, it is a visual indicator that a human has Honkai Resistance Adaptability. Stigmas originate from Herrscher's stigmata as scientists have replicated the visual marker through the combination of genomes. Those with high-level Honkai adaptability possessing stigmata can pass them through their bloodline

Herrschers - Entities that aim to destroy humanity. They are born from humans with high Honkai Resistance Adaptability and act as their "second persona' until they overtake their host's body, while there are also other ways. They possess a godly level of powers and can surpass S-Rank Valkyries which can be said to be the strongest. Their powers are condensed in a core or gem which signifies their authority and can be their only weakness. 

Battlesuits - Valkyries wear specialized armor that enhances their abilities. They can grant properties and elements to their function and grant new powers that they usually cannot achieve, it is a feature under Schicksal. [There are some people without battlesuits but have different forms, but I'll still put them under battlesuits]

Honkai Welts [HW] - Unit of Honkai Energy to determine the amount required for corruption and levels for the birth of a Honkai Beast or Herrscher. It detects the emission of Honkai energy and is used for surveillance or determining big attacks of enemies

Honkai Beasts - They are the materialization of Honkai who exist as monsters that destroy humanity directly, existing as silicon-based creatures, unlike humans being carbon-based. The common appearance is completely white with purple lines on them, like people with Honkai Sickness. They are divided into stages that define their destructiveness and abilities (it may not be accurate as some Honkai Beasts may evolve from their original paths). 

Vipralopa - Undefinable powers that are strictly stronger than Judgement Class Honkai Beasts that can handle multiple S-Rank Valkyries

Judgment - This type of Honkai Beast is usually created with the birth of a new Herrscher as each upcoming will result in the absorption of tremendous levels of Honkai Energy which a Herrscher and a specified Honkai Beast can absorb

Emperor - They are massive and highly destructive with a special ability or trait that aids them in their cause. Generally, they arrive under the conditions of Honkai Energy being within 1000 HW, requiring a team of A-Rank Valkyries or a single S-Rank Valkyrie to handle it

Templar - Valkyries below A-Rank must be in a team to handle it. They are the passing test to become an A-Rank Valkyrie. Their appearances are similar to their names, having high defense and attack with a shield and spear

 Chariot - Commonly existing Honkai Beast that can be dealt with a single B-Rank Valkyrie. They possess a wide body and mainly the grunt in a horde that defends and attacks heavily

Knight - Honkai Beast with high mobility, a white figure will be riding in his stead and uses a lance to strike its foes. While having lower defense stats, they contain higher attack strength and use momentum to strike higher than their rank

Seraph - Small and common Honkai Beast that exists in groups. The wings are their only weapons as they possess high movement speed compared to their counterparts of the same rank
