Rukh

"Rukh is the home of souls. While we live, it is every man for them self. But when you die, all go back to one place, This is Rukh. When humans die, their bodies return to the earth don't they? The souls return to Rukh, The home of souls."

- Baba, telling Aladdin about Rukh

Guidance
When Life is born and it lives within the flow, to move forward one must accept that truth. This is Rukh's Guidance or "Fate". However there are people who try to go against it like the people of Al Sarmen. The degeneration of evolution, existence becomes nothing and for everything to become their negative that is what it means to go against Fate. This is also known as "Falling into Depravity". When one loved by Rukh is stained in black like Judal they have this power to change fate and can lead to the death of another Magi like Aladdin. Only the power of a "Miracle" can fight against this darkness. Only with Solomon's Wisdom will this miracle be possible. It is unknown if this mission applies to all Magi.

Black Rukh
Black Rukh is the polar opposite of Rukh. It is created when one goes against fate and tries to defy destiny. It is created from and fuels hatred and malice. The people of Al Sarmen are using it to change destiny as well as for creating Dark Metal Vessels. They hope to change the world with this. The Magi, Judal, is able to control it.

The people of Magnostadt have also learned how to use Black Rukh, but so far as seen the people of Magnostadt have not yet used Black Rukh, it is possible that they can use it but they do not exibit it freely.

Types/Traits of Rukh
Magicians and Rukh have some individual traits. The Rukh that cause the waves in the sea and the Rukh that cause the wind in the sky are different. Magnostadt has classified the infinite types of Rukh out there into 8 great categories like this:

''1st type: Rukh that manipulates flames. Magicians who have an affinity to this type are called "Red Magicians".''

''2nd type: Rukh that manipulates water. Magicians who have an affinity to this type are called "Blue Magicians".''

3rd type: Rukh that manipulates light.

''4th type: Rukh that manipulates lightning. Magician who have an affinity to this type are called "Yellow Magicians".''

''5th type: Rukh that manipulates wind. Magicians who have an affinity to this type are called "White Magicians".''

6th type: Rukh that manipulates sound.

7th type: Rukh that manipulates power.

''8th type: Rukh that manipulates life. Magicians who have an affinity to this type are called "Purple Magicians".''

When the Rukh for a type are used they shine their respective colors. For example, the Rukh of the first type shine with a red color for humans eyes when they cause a natural phenomenon. For that reason, the first type magician is called “red magician” as well.

Trivia

 * The name of this concept (Japanese: ルフ rufu) is a sort of play-on-words derived from two Arabic words: رُخ rukh ("rukh" or "roc" - a legendary mythical bird of Middle-Eastern origin) and رُوح ruuh ("soul").
 * The Persian term "rukh" was the original name for the rook chess piece, though it has very little connection to the mythological rukh.
