Avant Heim (アヴァント・ヘイム, Avanto Heimu) is the location where the Flügels reside. Regarded as the largest library in Disboard, it is a city floating in the sky, but simultaneously, it is also one of the Phantasma, a sentient being form a part of the Ixseed. After changing into a floating island after the beginning of Ten Covenants, it can transform into a menacing flying fortress armed with numerous cannons capable to unleash destructive barrages.


Avant Heim's structure is made of a huge number of cubes stacked up in a complex and irregular way, making navigation difficult. It also has no roads, as Flügels can simply fly or teleport themselves. Stephanie Dola realized that the city has the poorest accessible environment compared to the technologically supported Eastern Union and even less than the Elkia Kingdom. It is decorated with a skull of a Dragonia with a ribbon on it. This is the skull of Lichtengärte, the Dragonia that Jibril killed by herself.

Avant Heim is known to have a very vast library as well, being much larger than the National Library of Elkia. The library is primarily owned by Azriel and it's in a large mess, since she doesn't care much about the books themselves. According to Azriel, once you have read and memorized the content of a book, there's no need to re-read and the book itself is pretty much redundant. Jibril strongly disagrees with such ideology.


Avant Heim was a former protege of the Old Deus Artosh. Along with the Flügel, he aided the god of war into nearly seizing the throne of the One True God. However, it was never accomplished as Artosh was slain before they could capture their prize. He could not accept his master's death and has since been attempting to reach The Red Moon where the Lunamana reside due to the presence of an Old Deus there which he mistakes as Artosh. Avant Heim does not simply float, but "swims" on the spiritual lines of Disboard (which is why he can't ever reach the moon). Avant Heim weeps whenever The Red Moon shines full and draws near a location where he feels the presence of an Old Deus, hoping one day he can be reunited with his master.


  • The author has tweeted that 'Avant' comes from modifying the pronunciation of 'abandoned'.
  • Kuhaku soon referred Avant Heim as Laputa, a floating castle written by famous animator Hayao Miyazaki.
