Hallicon
A fluid that makes up the body and limbs of every object. It can stay rigid (to form limbs), or perfectly mimic a material's every trait (to form bodies or therian limbs). Hallicon contains vital functions and memories, so missing limbs or major parts of the body will impact an object's life. Objects can store things in their limbs' hallicon like pockets.
Therianthropy
A normal objects' ability to switch into an animal-like form, called a therianform (as opposed to their standard form). This may come with changes to their object. In therian form, objects have wide, pupiled eyes.
Hypertherian
A large object who only has a therian form, due to a birth condition that triggers feral DNA. Hypertherians have health complications and may act more rambunctious than standard objects. They are recognizable by their large eyes.
Feral
A species of object that serves as an equivalent to real-life animals. They have no standard form and act and think exactly like their animatype. They are recognizable by their small, circular eyes.
Divine Object
Divine (or angel) objects are the only objects who can manipulate angel energy. They cannot bear children, and instead reincarnate after death.
Elythrium / "Angel Energy"
A crystalized energy that can instantly generate, move, alter, or destroy any matter. Contact with it improves an objects' physical resistance.
Myrellite / "Astral Energy"
A mysterious crystal shaped energy that takes the shape of stars. If touched, it will give you a terrible illness. Further research is required.
Myrellyth Fractal
A small crystal alloy of Myrellite and Elythrium. The Elythrium is used to stabilize the Myrellite, allowing it to be safely handled. The crystals grant a certain power; only the person carrying the most crystals will have full control over this power. Further research is required.
Demon Object
A lesser kind of divine object. They require physical contact with angel energy to use it, and even then cannot use it as well as angels can.
Mechanical Object
Robotic objects created by angel objects. They are made of hallicon wrapped inside mechanical parts and are built to varying levels of quality and humanity, depending on when they were made and for what purpose. Unlike their creators, they can bear children. They're typically considered 'creations', though some angels may consider some mechanical objects their children.
