The Royal Momju Necklace is a magical item that originated in Korea. Originally made by a king for his daughter, it allows the wearer to read and control the minds of others. The necklace is simple thin gold chain while the rings are simple gold bands. The rings magically adjust to the wearer's finger once they put them on. Once it is on it cannot be taken off by anyone but the necklace wearer either by command or phyiscally. The necklace itself is bound by the blood of wearer and only that wearer can use it. To use it to its full extent the necklace wearer must have a high level of mental control obtained through genes and years of training from a very early age.
The necklace's powers work on anyone wearing a special ring. The ring must be worn and the person wearing it must have willingly accepted it, though they do not need to know what it will do. The ring is essentially a mark of servitude to the wearer of the necklace, which is a symbol of royalty.
The necklace wearer is able to, with concentration, read the mind of any person wearing a ring. Thought, feelings, even hidden secrets are all revealed.
Not only can the wearer of the necklace read minds, but it allows them to manipulate them as well. Through will alone, though vocal orders can help, ring-wearers can be commanded to do whatever the necklace-wearer wishes. The control goes beyond simple commands as well, allowing for a person's very personality to be altered. The ring-wearers can also be made unaware that they're being influenced.
If in a safe location the necklace-wearer can move their mind to that of a ring-wearer, leaving their own body in a state of suspended animation. The possessed person's mind is surpressed, allowing the necklace-wearer to have direct control over the person's body.
A ring-wearer can be placed in a state of suspended animation by the necklace-wearer, freezing them in place. Anyone suspended has their natural bodily functions all stopped, allowing them to remain in the state for a long time without problems arising.
In a rare case that the ring-wearer is free from it, the necklace bearer could implant final thoughts and memories into their minds. They could even alter their personality once more if desired. These changes and implants will remain as if always there once the ring is off.
