Avant Heim

Avant Heim (アヴァント・ヘイム) is where the Flügels reside. It is a city floating in the sky, but simultaneously, it is also one of the Phantasma, and thus a sentient being as it is part of the Exceed.

Avant Heim translates into 'First Home', with 'Avant' as 'first' in French, and 'Heim' as 'home' in German.
