Selinos' magic system

Selinos' magic system
Only around 1/4 of the Selinos's population can use magic, however everybody has a crystal core, when you die it shatters and the shard of the crystal that held magic returns to the earth. Everyone's shard holds magic it's just that not not everyone can manifest it into a useable form.
Only two shards of your core is magic that you can harness they are called a soul shard and a nova shard. Some people have large soul or nova shards and can use large amounts of magic others have small shards and can only use small amounts of magic.
While two shards of your crystal hold magic, your soul shard holds magic that is drawn from you as a person can use while the nova shard holds magic that is drawn from the earth and hence returns to the earth to power creatures and places.
However only one of these shards can be used and you don't get to decide. People who harness the power of a Nova shard have magic that allows them to control elements, talk to animals, breathe under water, super strength, speed,or breathe different elements.
Whereas people who use soul shard magic can; read minds, predict the future,
Speak with the dead, use telepathy, medium related powers, empathy , telekinesis, and illusions.
In extremely rare cases some have been able to use both a soul shard and a nova shard's powers. This has resulted in powers such as pyrokinesis  (this is strange considering that the fire has to be already present to be able to manipulate it) shape shifting into animal or healing from one touch.

Overall the main difference between a nova and a soul shard is that; soul shards hold no physical form over the wielder whereas nova shards do. So a soul soul shard will let you  draw magic from yourself but a nova shard will let you draw it from the earth.

Factors of soul shard drawing:
.Emotions e.g hate, happiness, guilt, sadness, fear etc
.willpower
.courage
.strength of heart

Factors of nova shard drawing:
.strong connection to element
.strong connection to environment
.highly powered environment
.area with high levels of magic

As most magic energy has dispersed into the atmosphere and further regions of space a nova shard wielder in space would be able to draw massive amounts of energy. However space travel is not yet possible and so this is the reason there isn't a nova shard wielder ruling the entirety of selinos.

100s of years ago the whole population could harness magic however after the supposed extinction of demons, as a result of the holy war between angels and demons in which the humans were forced to join, magic was mostly absorbed and dispersed into the atmosphere. Now only 1/4 can harness magic and those who cannot despise those who can.

As magic is very rare to harness it is banned in almost every continent excluding merfolk, elven and fairy populations. This makes practicing magic very difficult without a mentor and leaving children with strong amounts of magic losing control at sudden changes of emotion.

Star circus:

Star circuses in Selinos

S.T.A.R:
Shard
Tracking
And
Restoration

Star circuses aren't your average circus, they are far from it. The purpose of having star circuses I'm Selinos is to obtain shards that have drifted from a core.
Shards that drift from a core are extremely dangerous, if they are absorbed by a non shard wielder they will overflow with power that cannot be controlled and destroy everything in sight. Likewise if an animal absorbs a shard that is either opposite to the current shard they draw magic from or if they are not of a magic species.
This is why shard tracking and restoration groups known as S.T.A.R's were formed.
As magic is banned in many countries in Selinos the star circuses work in secret to keep the flow of magic in balance. Many do not believe in star circuses and say they were just made up after the holy calamity.
However, star circuses are required to have teams of at least three when collecting shards. As people who can use magic either harness a nova shard or a soul shard it is important to have multiple wielders as a soul shard wielder cannot absorb a nova shard and vice versa.
If a shard is absorbed it is required that said shard is dispersed into Selinos through a shard slot. These were created 1000's of years ago before the holy calamity. A stone altar, the wielder must put the shard into this otherwise the wielder will go mad.
With too much magic a wielder will go crazy and eventually turn into a demon.
If a STAR does not disperse of the shard within 1 week of collection then the remaining members of the circus will have to exterminate them as they would have already begun the transformation and gradual descent into a demon.
When a STAR absorbs a shard they place there palm on the altar and within 10 minutes the shard has returned to Selinos.
When the shard returns to Selinos it will either find an unborn human's core to latch onto or become an environmental element (form depending on the previous core, for example if the shard belonged to a fire controller then the shard becomes a fire element and thus the cycle continues)
If a wielder has pulled their hand away from the altar before the 10 minutes required is up then the shard stays with the wielder.
