This is a very basic amnestic that gets rid of memories that happen 5 to 6 hours prior. It's often used on people who have seen anomalies. The officer in the area that's giving them the amnestic can actually retrigger these memories and erase them again if need be.

Class A, General Retrograde:

Class B, Regressive Retrograde:

This amnestic is used to erase memories that happened 24 hours prior. It's used if the memories are beyond the 6 our period that the previous amnestic handles.

Class C, Targeted Retrograde:

Although this anesthetic isn't distributed much due to lack of resources, Its main functionality is that it removes specific memories regardless when they happened. It allows foundation to remove classified information if need be.

Class D, Progressive Retrograde:

Class amnestics are rarely used, but their function is that they remove the earliest memories in the subjects mind.

Class E, Ennui:

Ennui isn't the proper word for this as it's described as an "anti-nostalgia" amnestic. This one is more psychological as it changes the memories in your brain and either a positive or negative way. The end result is that it causes the subject to perceive the world world as it is, Not seeing anything weird or strange as they don't remember it that way. Essentially if something is freaking you out because it's scary or weird they could use this and you would see it as normal.

Class F, Fugue:

The amnestic in this case give the subject amnesia. Once the person loses their identity they're either given one by the officer there, or they're allowed to develop an identity of their own.

Class G, Gaslighting:

Used for non anomalous memories, This mystic is quite controversial. It causes the subject to doubt all of their memory. Not knowing if they are truly authentic or not.

Class H, Anterograde:

The nature of the synestic prevents the subject from gaining any new memories. The effect usually lasts about 24 hours unless given another dose.

Class I, Transient:

Unlike the Class F amnestic, this one gives you temporary amnesia for about 24 hours.

Class W-Z, Mnestics:

This one protects against mnemontic anomalies and anti-memetic agents. W allows the person to perceive and retain knowledge of antimemes. X restores awareness of the person after perceiving antimemes or it suppresses memories. Y allows the subject to recall any memories while it's in effect. Finally Z, it disables the subject to forget anything for the rest of their lives. It's also fatal since most subjects die hours after receiving it.

For anyone who doesn't know what this means, when hlvrai had the gag about benrey editing Wikipedia articles. The fan base started adding this in.
