When I was just starting on Shattered Planes Zak requested something that I personally thought was genius. That thing was an anti magic shield. I had thought it was a cool idea, and the more I learned about SP, the more I realized it was a real necessity. Magic is the ultimate power on Shattered Planes. Anything you make in Technology can be beaten by a powerful and clever mage. Anti magic was the only was to stop it, and the only check in this system of checks and balances. Unfortunately, I somewhat recently heard of anther check that makes this system of checks and balances unbalanced: Anti anti magic. There are ways of keeping your magic through an anti magic shield. Weather it's concealing it inside you, or a portable bit of technology, I think that guarding magic from anti magic is nothing of a priority. What we really need is a way of guarding anti magic from magic to protect anyone magically inferior. Technology is what's become something that's inferior, and without anti magic, all the tech in the Archive is meaningless if you were a level 6, or even a level 5.
When the Heliphlein were living in the time around the first bad torment spikes that were to change the nation forever CODE was on the case for finding a way to solve the problem. One of the things they developed were anti magic fields. Simple fields that dispensed a form of Anti magic that would reverse, and therefore stop, the magic from working inside the people. They gave up on this though, mainly because they couldn't get it to the whole community without disabling non tormented magic users. They had it discontinued for a while.
A few hundred years later the Heliphlein police forces figured out that they could use anti magic fields to incapacitate fugitives. They put them up in prisons all across the Nation. Unfortunately the Enrakni, which sadly filled the majority of the prisons, figured out that they could channel magic inside them and be able to use it if they wanted (for example, to get free). The police and wardens wanted there to be a way to stop that, and after a while, CODE found a way. That solution was AMI.
The CODE scientists found out that the Anti Magic that they were using was much more powerful in a liquid form. This was partly because it was more concentrated, and also partly because most living things are mostly made of liquid. The CODE scientists then had a genius idea of how to help incapacitate criminals: make the liquid form into an injection.
The formula took off. When injected with this formula the anti magic would flow through the bloodstream to every part of the body, and any magical resistance of it would be shut off when it came into contact with the anti magic as it flowed through the bloodstream. If they were injected in the arm, then any magic flowing through the arm would be cut off. Any magic that came into contact with the blood in that vein would stop. It would just stop. As the blood would flow through the bloodstream, the other parts of the body would loose they're magical ability. After twenty minutes all the magic in the body would be gone, and it wouldn't come back for about twelve hours. Unfortunately for most prisoners, this would mean that they couldn't store up magic inside them, and twelve hours later they would be inside an anti magic fielded prison. Being inside an anti magic field would then render them unable to heal or restore they're magic until they left it.
After using it in the field a few years, the Heliphlein police took it in a natural direction: handcuffs. After a while of cops complaining about how hard it is to inject a criminal that's using magic to try and get away, a scientist at CODE designed a pair of handcuffs that could hold and protect from breakage not one, but two syringes in it. This made it easy for police to take the prisoners into custody because when they cuffed the criminal, the criminal couldn't break the cuff with the ease of magic. Crime rate went down for a while, and now the main focus is just to not get caught.
