Djinn

Djinn (ジン, Jin) are artificial life created from Rukh. Originally they could only be created from magicians who are loved by Rukh or Magi. They rule over Dungeons. They sleep deep inside their Dungeon, until a Dungeon Capturer reaches where they are. They are able to change the level of their Dungeon's difficulty. Yamuraiha has stated that there is a bad affinity between Djinn and Magicians. That in a certain sense Djinn are magic users too and if a magician uses a djinn, their magic could interfere with each other.

Dark Djinn
Al Sarmen has discovered a way to use the Dark Rukh to create their own Djinn transformation technique. By stabbing oneself with a Dark Metal Vessel they can summon the Dark Rukh and transform, this however can only be done by sacrificing one's life. Dark Djinn are able to heal forever as long as there is a supply of Dark Rukh.

Trivia

 * The Djinn are based on the Djinn, also known as Jinn or Genie, from the Arabian and Islamic mythologies.
 * The Djinns were created by Solomon in Magi. This is based on the Islamic view of Solomon, according to which Solomon ruled over an army of Djinn.
 * Their names, excluding Ugo and Black Djinn, may come from the names of demons in Ars Goetia, part of the Lesser Keys of Solomon, who in turn is the creator of the Djinn in Magi.
 * The name of "Ugo" could be from the French poet Victor Hugo, who wrote a poem called Djinn.
