Quanta representation :
"Quanta and miasma have both been forever inhabiting the universe when the world appeared in the middle of the miasma. It was composed of dense, very dense miasma, and it was solid. Both quanta and miasma concentrated around the world, mindlessly. As they closed in, they started to mingle, forming the elements. As the raw quanta changed to be elemental, it started to affect the fabric of the world. Many natural laws were born, but most importantly, it started shaping the world, giving it more than just shape, but substance too. Eventually, the portions with more miasma than quanta started making the substance, creatures and permanents being born, while the more quantic part started making Elementals.
Millenias after, while the miasma still was generating creatures and permanents, the Elementals began to understand their nature. Slowly, they discovered that they could change, stop being pure quanta and instead become aligned elementals. Rapidly, the number of pure Elementals diminished, till they disapeared. Only then did the Elementals see that they could not change their nature once it was chosen. There the Bazar appeared. It was a strange place, filled with strange objects and even stranger personns. These personns, however, were very clear : for a consistent sum of electrum, it would change Elementals. They also sold the first cards, and thus the first duels began.
With the first cards, the Elementals started to understand that quanta was a whole lot more than just themselves, that it was energy in the purest state. They understood, for example, how pillars worked, why they burnt an elemental, but soothed another. They also understood what Miasma was, and how, with their natural attunement to quanta, they could shape them, even without cards. They tried duels without card, and learnt (at their cost) all the rules of a duel. They also started to understand that quanta was not something they could count, the quantities always too great or too little. Besides, they didn't need to, due to their intuitive apreciation of it.
One day, a Darkness elemental, pure in the power of his kind, challenged a bazzar maintener. The creature, after a moment of thought, agreed and brought up a deck. After a very tough match, the bazar creature lost, and thus had to give the secret of mark change, as well of quanta, to the elemental. He immediatly dispersed the news, and soon, everyone could change his inner heart for free. Few did, however, and even rare were those who did it in other circumstances that duels."
