Ragnarök

The Ragnarök Connection, also known simply as Ragnarök, is a term initially uttered by the Emperor of Britannia when Lelouch forms his Geass contract with C.C.. With the use of the Sword of Akasha, the Thought Elevator, and two Codes, the Emperor can force the collective subconscious of human beings onto the surface of their mask and affect reality, making all humans, both living and dead, into one being. For this reason, the Emperor connected every thought elevator on the planet. He then intended to unleash Ragnarök using the thought elevator in Kamine Island. This contract was made between Charles zi Britannia, Marianne vi Britannia, C.C. and V.V., where they would destroy the gods and unite all humans, living and dead into one being. This plan was thwarted by Lelouch vi Britannia when he used his Geass to compel the gods to keep existing and to keep time moving. This resulted in the death of both of his parents.

Similarity In Other Media

 * The concept of Ragnarök is very similar to the Human Instrumentality of Neon Genesis Evangelion, both in the idea and the way it is carried out, a plan where a secret cabal of the worlds' elite and powerful work to unite all of humanity into a single entity with the purpose of evolving/saving it. The major difference is that Ragnarök united all beings, living or dead, while it's up to interpretation if the Human Instrumentality Project united only living humans or if it united all humans who ever lived. Another difference is that Ragnarök was ultimately stopped, while the Human Instrumentality Project was partially successful.
 * Ragnarök is also the name of what is essentially the apocalypse in Norse mythology. People would supposedly lose their senses and commit all kinds of atrocities. Many of the Gods died. Odin is swallowed whole by Fenrir, Fenrir has his jaw destroyed and his heart stabbed by Víðarr, Jörmungandr (the world serpent of Midgard) and Thor meet in combat and kill each other, Freyr dies fighting Surtr, Týr and the hound Garmr kill each other, Loki and Heimdallr kill each other. Surtr sets the world on fire, and the earth sinks below the sea, killing all but two people. Eventually the earth rises from the water beautiful and lush, and is repopulated. This somewhat mirrors Charles' plan, killing the Gods and essentially destroying humanity to remake it into what he perceives as beautiful and right.
