Okay so... I only have the history but the history explains my entire idea for the magic system (Also this is from in-world, so they have some weird names for stuff) (Oh yeah also WaT and Mistborn spoilers):

Timeline:

Before The Split & Context: There were people born with magical powers that had unique abilities. These people are called Shardmancers. There are strange metals found throughout the ground that do strange things when ingested. Shardmancers awaken (think snapping) their abilities when feeling a strong emotion.

The Split: All of the Shardmancers suddenly felt a strong shock through their bones. They felt their entire body convulsing at the very nature of some cosmic event. Then it ended. Suddenly, all the Shardmancer's powers changed. There were then 16 types of shardmancers. Each with unique abilities. They all had some abilities, just some types were stronger at them then others.

The First Crackling: All of the Commited (Type of Shardmancer) Shardmancers and the Controler (Type of Shardmancer) Shardmancers suddnly felt a similar strong shock. This time, it didn't stop. All of the Commited and Controler Shardmancers became the first Instables. The Instables kept their original powers, but they were mentally unstable and were slowly dissolving (Think Soulcaster Savants).

The Second Crackling: Everyone was terrified. They thought this was a sign of doomsday. They prophesized that in 1000 years, another Crackling would happen. 1000 years went by and nothing happened. People started to think it was a one time thing. Another 1000 years later, the Second Crackling occured. This time, it was the Driven. The Driven, too, had become Instables. Now 3 of the 16 types of Shardmancers were are curse, and not a blessing. People were incredibly worried.

The Third Crackling: At an unknown point in history all of the Kind Shardmancers also became Instable (Yes I did put this in last minute

The Sealing: Near the begining of the Rippling, all Destructor Shardmancers lost their powers. They could still feel their powers, and access them, but it was incredibly hard too, and they couldn't use them much.

The Rippling: The rippling happened an unknown time afterwords, but all the Stagnant Shardmancers felt their power slowly going away and becoming weaker. This was a long event that also seemed to progressivly make the Stagnant closer and closer too being Instable. Right after the Rippling, the Confusion struck.

The Unsealing: Near the end of the Rippling, all Destructors regained their powers fully.

The First Confusion: All of the Stagnant felt the strong shock for a brief moment. Only days or weeks later, they felt it again. Then, AGAIN! This was very confusing. But after the last shock to the Stagnant, the First Binding began.

The First Binding: In the Confusion, the last shock was felt by the Destructors too. Then, for the first time in thousands of years, a new power emerged. Any Shardmancer had a 2/16 chance to be a Connector. All of the Stagnant and Destructors became Connectors. The Connectors were unlike other Shardmancers and when using their powers, you had to keep strong mental stability and concentration to use the powers. Otherwise, If you use your powers for too long, you will become a Disconected.

The Second Confusion: All of the Anger Shardmancers felt a shock again but thought nothing of it. Only weeks later, the Oath Shardmancers all also felt a shock. Then, only days after, The second Binding began.

The Second Binding: At the end of The Second Confsion, the Oath and Anger Shardmancers became the Punishment Shardmancers. The Punishment Shardmancers are slightly unstable.

Also, this is my favorite magic system so far. Won't use in many RP's though
