This page will be filled with terms, places, and other bits of information in the case someone does not know what each thing means.

Statistics

Brawn - The physical strength and non-magical fighting capabilities of a character.

Brains - The intelligence of a character.

Hustle - The endurance and speed of a character.

Guts - The damage tolerance (or HP) of a character.

Charm - The charisma of a character.

Occult - The magical capabilities of a character (relative to a normal human).

Boss Monster - From undertale, examples would be Toriel, Asgore, or Asriel.

AI - Artificial intelligence, I commonly split this into C, B, and A grade AI

A-Grade AI - AI that constantly learns from every piece of its surroundings, and can rewrite it's own code, leaving it with limitless potential, and often leads to dangerous actions from the AI

B-Grade AI - AI that can learn from most of its environment, though it cannot rewrite itself like an A-Grade. B-Grade AI are almost always found with a personality programmed into it. 

C-Grade AI - AI that can only learn from very specific pre-programmed inputs, or sometimes not at all. Some C-Grade AI will have attempts at personality programmed into them, they do not function as actual personality as protocols and programming will override it. Nearly all real life AI fall into the description of C-Grade.

Magic - We all know magic, but because I commonly use terms not everyone can immediately understand, I'll be explaining them.

Active Magic - Active Magic is any kind of magic that doesn't happen automatically, the opposite to Passive Magic. Active magic needs to actively be cast for it to function, throwing fire, creating objects, etc. While Active Magic can be trained into a reflex, it still is not automatic and will always fall into Active Magic category.

Passive Magic - Passive magic is any kind of magic that doesn't need to be actively thought of to be used, the opposite to Active Magic. Usually a Passive Magic will be an increase in a normal skill, better sight, strength, speed, etc.

Target Magic - Target Magic is magic that requires a target to be used, this can be anything from lighting a specific object on fire, or changing it's gravity, to immediately destroying it.

Non-Target Magic - The opposite of Target Magic, it doesn't require a specific target to be used on, this can be anything from creating an object to changing the temperature of a specific area. (No, the air does not count as a target in most situations.)

"Universal Folders" - What I commonly refer to the different pieces of the multiverse with.

Timeline - Timelines are the smallest portion of the universal folder, being the single version of a world. Timelines are differentiated by different actions taken in each.

Universe - A universe can be thought of as a folder that timelines can fall into, a universe will dictate the scenario, characters, or other large elements everything occurs with, while a timeline dictates what happens in it.

Multiverse - The largest folder, contains every universe in it. 

Dark Fountains - From Deltarune, a dark fountain can be created by anyone, and will use objects in the space around it to create a miniature world.

Cyberpunk items and characters

Shard - An item from cyberpunk, used to contain large amounts of information and easily transfer said information between people. Shards can contain anything from text documents to knowledge in a certain field. Some Shards have reflexes coded into them, if a shard containing reflexes is removed, the reflexes are removed as well.

Engram - A digital copy of a person, can be used either to overwrite the personality of a person or to copy a personality of a person into a device or other person.

Maxtac - The cyberpunk equivalent to special forces

Trauma Team - The cyberpunk equivalent to emergency care, though on a subscription based service rather than a government owned healthcare solution

Destiny 2 Things

Strand - Not explaining the Weave, but it's something that links one to a ton of invisible string, ropes, and other forms of strands that most cannot see, letting one use them to either attack, or just as movement. Also this is a Darkness based subclass.

Arc - The electrical based subclass of the Guardians.

Solar - The fire based subclass of the guardians, letting them use the literal power of the sun to fight.

Void - It's a Guardian Subclass based on the void, black holes, etc.

Ghosts - Tiny mechanical looking creatures created by The Traveler, they utilize The Light to act as a Guardians connection to The Light.

The Light - Good question. Best I can do to explain is say it's a force of nature that uses concepts (Time or "The Weave") to enact it's will.

The Darkness - Good question. The best I can do to explain it is say it's a force of nature (tf2 reference) that acts using elemental forces.
