Ninth Layer of Hell

'''SPOILERS AHEAD! READ AT YOUR OWN RISK!''' The Ninth Layer of Hell, also known as the Ninth Circle of Hell, or the Ninth Sphere of Hell, is a section of Hell that is implied to be somewhere within Verloren's core. The revered god and archangel Mikhail constantly threatens to take his opponents to this place, with the implication that this is not an idle threat.

Book of Hades
The Ninth Layer of Hell and the Book of Hades seem to be connected to each other, as Ea can send souls to the Ninth Circle of Hell if he determines the severity of their actions has warranted it.

Time
According to Eve, time is an unstable element within the Ninth Sphere of Hell. She notes that even though Landkarte has spent decades within it, only moments have passed in the real world.

Ascension
Although people who commit terrible crimes are sent to the Ninth Layer of Hell as punishment, they can ascend to Heaven if they acknowledge and admit their wrongdoings, or if it's the Chief of Heaven's will.
