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

Rukh (ルフ, Rufu) is the main source of Magoi and the world's natural phenomenon.

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-Thamen. 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 Judar, 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 the Wisdom of Solomon will this miracle be possible. It is currently 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-Thamen are using it to change destiny as well as for creating Dark Metal Vessels. They hope to change the world with this. The Magi, Judar, is able to control it.

The Al-Thamen incoporating with Magnostadt in the past, discovered how to create a Black Djinn, using the Black Rukh.

It is revealed that the Rukh that comes from the people who died, while being in the state of "Depravity" cannot go back to Great White Flow.

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".''
