SOUL Subjugation Band (SSB) - The inventor is Dr. Zalphys. She was inspired while reading comic books. - All patients have this attached to their SOULs upon being registered into the UnderJail Correctional Facility Systems. - This magic restriction system is in place so that patients don't harm others or themselves. This restriction only affects the casting of most magic. It doesn't affect the composition of the patient (so Grillby with an SSB would not look like a walking match with no fire). - The main UJCF staff member that is tasked to do this is Zoriel, but Zans, Dr. Gaster, and Zalphys can do it as well. Zoriel is selected primarily due to her ability to calm patients during the proceedure (it’s very invasive and most patients aren’t exactly willing to have their magic restricted). - The default setting is LV. 3 - BLUE. It can be set lower or higher depending on the patient's behavior. Good behavior can earn LV.1 - WHITE. - LV. 5 - BLACK is not part of the original programming of the SSB. It was added in after Dr. Gaster was hired. Due to this, only Dr. Gaster can change the SSB's LV into and out of BLACK. His official reason for wanting the additional BLACK LV. is that you can't simply slap the wrists of certain patients for being non compliant. - The amount of damage the patient receives from this level depends on the level of malicious intent. It's a lot if there's a lot of malicious intent, and a little if it's not. Due to this, it is impossible for the patient to heal themselves while their SSB is LV. BLACK. There is a fail safe installed by Dr. Zalphys at the request of Zoriel that if the patient tries to use so much magic to the point of nearly Falling Down, the SSB will switch back to LV. VIOLET without any input from Dr. Gaster. It also can't be changed back to BLACK until the patient is properly taken care of. - Zoriel believes LV. BLACK is extremely cruel and thinks it can cause severe psychological issues. - The white band wrapping the SOUL changes color depending on the Risk Level of the patient on a scale of 1 to 7. More on Risk Level later. If you made it this far, I will give you one bit of spoiler: UnderSwap Sans is a patient and his "glitch" is that he has anthropophobia and very prone to anxiety attacks. Speculated to be caused by his UnderSwap Papyrus being very very abusive towards him (yes, UnderSwap Papyrus is also a patient). Doggo (who is staffed at UJCF) is one of the very few who is able to get near US Sans without him going into an attack. US Sans petting Doggo is therapuetic. UnderFell Sans is also a patient and his issue is that he doesn't like mustard. As you can see, patients are patients no matter how large or small they different from their accepted AU canon.
