The plot of the show was around a secret warehouse, filled with mystical objects that each had a special ability of its own. Each object has a good and bad side to its effect, so that makes all of the objects dangerous to use. At all. So, the objects need to be collected, tagged and placed in the secure place that is Warehouse 13.

I plan the roleplay to be based in Warehouse 13, only without any of the canon characters or story. If this happens after those characters died, retired, or simply never existed, I will choose later, but my point is that I want fresh agents, fresh Caretaker, and a fresh, new story. This will be our warehouse, our artifacts to play around with.

The Warehouse is a large facility in South Dakota that is able to constantly expand the amount of items held within it, due to being placed right next to a mountain and being underground. It has many different sectors, depending on the objects stored and how dangerous they are considered to be. There is the main area, which contains most of the general artifacts, and it can be considered extremely large, being as far as the eye can see. While it does have an actual end, it is very easy to get lost in it and think the place has no actual end. There are many smaller areas which contain artifacts according to either a time period, being extremely dangerous, or just plain whacky.

The Warehouse is run by a group of people known as the regents, who are a group of average people from all around the world, and they make the large choices for the Warehouse, as well as ensure it runs smoothly. Along with the regents, there is a single person known as the Caretaker. The Caretaker is the person who is directly responsible for the Warehouse, being in direct contact of it and the people running it at all times, when he or she are needed. The Caretaker is given certain special abilities to ensure he has a special connection to the Warehouse, and only very certain people can be chosen.

When it comes to collecting the artifacts, tagging them and managing the inner parts of the Warehouse, there are agents. There can be any number of agents at any given time, and they are only granted access if they were invited by the Caretaker, after the latter has deemed them to be right for the job. They go around the world, chasing the artifacts as they appear on the surface, and after they manage to ensure it harmed no one and move it safely to the Warehouse, they tag it and then place it in the appropiate place, which is usually defined pre-maturely to the artifact's arrival. Once in its proper place, the agents go on to the next case.

There are many more secrets to the Warehouse, and each section that I explained about has a lot more detail to be known, but this is the basic about each section of the general knowledge of the Warehouse and how it runs.)

A regular object which was so greatly influenced by an act of the person using it, or by the personality of the user, that it inherited a power which similates the user's action at the time. It is possible for everyone to use most of the different artifacts, but some artifacts are more complex and have certain conditions that need to be met with first, such as, using the artifact on a person you dearly care for, or only on injured people, and so on. It is possible to break most artifacts and thus remove their magic, but some either require a certain way, or cannot be broken at all.

Most artifacts gain their ability at a single, defining moment of the person using it, like making their greatest discovery in life, saving a person, and such. Some can gain their ability after being used many times in the same manner and under the very same condition.

Each object gains both a positive and a negative reaction to it. An example would be John A. Macready's Sunglasses. Upon wearing them, they would gain invisibility to the naked eye, but could still be seen through a camera lens, but after removing them, the wearer would be blind for a period of time which is twice as long as the wearer had the sunglasses on. (Example from the show.)
