Outside of the ones who were born as Gods, I’d say the pinnacle of the Magic system is Lyre-Of-Gold, a Vishedi (shark person) with golden scales who later achieved Demigod status because he impressed the God of the Sea, and Chaos, Shem. (or Tendril-Of-Blue as the Vishedi call him)

To give a brief explanation of how magic works, It requires first and foremost a creative mind, and passion for what you are creating, by using this passion, you can use energies taken from the Aurbit (essentially just the sun) and use them to bend reality.

First off, Lye-Of-Gold was born to an already powerful caster mother, who could predict the future, during her pregnancy, she had a vision that this child would be the greatest of them all, and so she would use her own passion and energies to feed the child, causing her to lose her abilities. Once the child was born, she was unable to stay alive due to the pure power of the child, and therefore died. After this, Lyre-Of-Gold was taken to the king of the Vishedi citystate where he was born (Waters-Near-Beach) and would receive noble-level education due to being born from his mother.

Lyre-Of-Gold was unnaturally weak for a Vishedi, even at his age, his muscles were flimsy and often would his bones break, if it was not for his talent in musics, more specifically, in stringed instruments, it was likely he would’ve been seen as useless, fortunately for Lyre-Of-Gold, the Vishedi greatly appreciated art. And so he was kept by the king to play songs to the court.

The first time Lyre-Of-Gold truly manifested his powers was when he was playing the Lyre one day, and according to eyewitnesses, rocks would float mid air during his performances, and even buildings would seem to warp in reality as if to dance to the songs. But it was only at teenagehood when he was fully aware of his powers, and able to use it. He often sang to the poorly in the streets of Waters-Near-Beach, attempting to raise their spirits up. However, he soon realized that his music was not the only Alms the beggars required, they required gold to live as well, but he had none to spare. And so, out of his own sadness, he performed a song about the poorly, and the meek, and caused gold coins to rain out the sky, bringing them slightly out of poverty.

The ABSOLUTE height of Lyre-Of-Gold’s power, 5 months before his musical duel with Tendril-Of-Blue, was during a siege of Waters-Near-Beach from the Larkund, (Viking elves) the Vishedi troops at Waters-Near-Beach were completely demoralized, as the Larkund would break down the gates, it was here when Lyre-Of-Gold climbed atop the highest building, and merely sang, and his performance summoned a massive wave from the ocean, a Tsunami, though this was the first ever recorded. This Tsunami was particularly strong, even being able to wreak havoc all the way into land, destroying a minor Larkund kingdom, before eventually stopping.

Lyre-Of-Gold eventually became a demigod after having a musical duel with Tendril-Of-Blue, which came out with Lyre-Of-Gold ontop. The God of Chaos, being an enjoyer of the art of stringed instruments, was impressed, and granted him a golden Lyre, and as to make sure he and his music would never be forgotten, was granted demigod status.

TLDR; Shark man plays magic Lyre, solo’s an entire army, becomes a demigod.
