Nine Circles, the famous Zobros wave focused level that started one of the longest lasting level trend in GD's history.

Likely surprising to some, Nine Circles' decoration concept is actually not original. The concept of the level and decoration was actually inspired by an old Open Hexagon custom stage named "The Dragon Mayhem", which came out shortly before and also used Nine Circles by Rukkus as its song.

Despite this, Nine Circles became a classic in the GD community.
