Ithnan

Isnan (イスナーン, Isuna^n) is a member of the Al Sarmen. He also has some ties with Solomon.

Zagan Arc
Isnan is first seen coming onto the Toran Nation island as merchants, following Dunya Mustashim and Isaac. They entered the Dungeon after Aladdin and the rest enter. Once inside, Dunya and Isaac attack Aladdin and his friends, however Aladdin is able to create a mirage of him and Alibaba and fools Dunya into aiming her attack into an empty field. Alibaba strikes at Isnan and cuts his head off. Isnan's decapitated head produces a snake, which bites Hakuryuu's hand prior to their departure of the Dungeon.

Second Sindria Arc
At the banquet, the night Hakuryuu, Morgiana, Alibaba, and Morgiana returned from the Dungeon, Hakuryuu's hand fell off his arm. Out of his hand, Isnan emerged, with a lot of Dark Rukh.

Sharrkan immediately attacks Isnan, however his attack only enhances the problem as clones appear from the amputated parts. The clones aim their attacks at Sinbad and Alibaba, but are quickly defeated, however, the blood from the clones splatters on both Sinbad and Alibaba. It gives them the "Curse of Death". The blood will possess their blood vessels and dye their ruhk black, eventually transforming the victim himself into a completely different person ("falling into depravity"), as Isnan explains. Opposing the transformation will cause the black and white ruhks to destroy each other and rot the flesh. That being said, he "invites" Sinbad and Alibaba to become Black Kings and surrender to Al Sarmen's "Father". He says because of all the White Rukh in Sindia, he has trouble breathing, but he felt comfortable living inside Hakuryuu.

Isnan leaves Sindria, but he is unexpectedly confronted by Sinbad, who appears out a Teleportation Magic Circle.

Lightning Magic
He used a form of Lightning Magic to strengthen Dunya and Isaac during their fight with Aladdin and Alibaba.

Curse Magic
It is a magic that will possess a person's blood vessels and turn their Rukh black if it is white. They will the be reborn as a new person because there exist noone without darkness. Isnan stated that if you try to oppose the change Solomon's rukh and the black rukh will destroy each other in the person's body and their flesh will rot.

Flame/Heat Magic
He used some sort of flame magic to attack the people of Sindria when he invaded.
