Aethion

Aethion, otherwise known as the Expanded Multiverse, is a Bionicle Universe created when a Kanohi Olmak came into contact with a mysterious energy source while inside transdimensional space. The universe consists of eight planets:


 * Alarist
 * Promathus
 * Barrawahi
 * Atohune
 * Izumal
 * Tanuuk
 * Clysmax
 * Enigma

The eight planets are surrounded and separated by an energy field called Bluespace. The Bluespace is impossible to travel through, so the only transportation between worlds is used via Olmak Totem or, sometimes, Olmak Effect. Supplies between planets are transported by the use of Cargo Stars, which also act as 'suns' for the planets.

Creation
500 years before the events of the Cipher Chronicles, a Kanohi Olmak drifting through transdimensional space encountered a mysterious energy force. When the Olmak made contact with the energy source, a multiverse was spawned, taking bits and pieces from other universes and dimensions inside BIONICLE.

With the multiverse, eight planets were formed, each surrounded by the impenetrable Bluespace. The eight planets are considered to be alternate versions of themselves, each being radically different from each other in terms of geography. The planets have a stationary orbit, but revolve on their own axis, causing the effects of night and day.

Trivia

 * The Kanohi Olmak that created the Multiverse was from the Toa Empire Pocket Dimension, where Toa Takanuva left it in between dimensions during his escape.
 * Aethion means "Universe of Aether", which is said to be the substance of the fabric of existence.
