Anomalies are unknown occurences that happen due to world-shifting events or time manipulation.
Type 1 Anomalies are occurences that don't affect most things, but only affect certain objects. Such as: a bunch of roses turning into a bunch of lilacs. (skip to 6:30 for info)
There are two subtypes for Type 1 anomalies.
Type 1A anomalies are the most normal of the Type 1 anomalies, usually affecting only certain objects.
Type 1B anomalies are the most uncertain Type 1's, usually affecting certain people or changing certain major objects, examples include a computer warping into a portal to a dimension.
Type 2 anomalies affect humans, usually either giving them powers or taking away powers. These are minor effects but add up to a major effect later on in that person's life. Examples include a person falling through a paved road whilst crossing it and gaining an ability to phase through objects.
There are two subtypes for Type 2 anomalies.
Type 2A anomalies are the most normal of the Type 2 anomalies, usually affecting only strong-willed people.
Type 2B's have been studied thoroughly and it is known that when these happen, it affects the people within a 50 meter range of it, giving them powers or taking them away.
Type 3 anomalies are the most effective kind of the three classes. They are usually spawned from global-level threats like Stalker, or dimension rips.
There is one subtype for the Type 3 Anomaly.
Type 3A anomalies are shown to be the cream of the crop for anomalies. They can affect nations and are shown to have traumatic effects on people who experience them. These anomalies include merging of souls into one body.
