Teleport Incident

The Teleport Incident, also known as Metastasis Event is a Mana calamity that occured in the Fittoa Region, Asura Kingdom in K417 which resulted to its citizens to be teleported to random locations on the world. The incident caused an innumerable amount of casualties and the first turning point in Rudeus Greyrat's life in the series.

Prelude
In K412, a red orb appears floating above the Boreas Estate in Roa and there is no known history recorded of such occurrence in the past. In a conversation with Rudeus, Sauros tells him that it's not a bad thing and that it is better to be left at that. Over the next three years, Rudeus notices that the orb seems to be getting bigger but overall the daily life and activities of Roa's citizens goes on.

Cause
The cause of the Teleportation accident was actually the result of events taking place roughly 80 years in the future. At this time, a certain nation was embroiled in a war and used the power of an individual known as the "Playback Miko" to summon a boy named Shinohara Akito from another world, whom was prophesied to be their savior. The Miko would grow close to the summoned boy and eventually develop feelings for him. Unfortunately, Akito was just an ordinary person and ended instantly being killed when the country forced him to step onto the battlefield. Overcome with grief, the Miko burnt out her power, to bend time and space, to alter the world to one where she and Akito might live happily together.

To successfully alter history, the Playback Miko reached out with her power and found an individual with similar feelings for Akito as herself: his girlfriend, Nanahoshi Shizuka. She then attempted to summon her to her current location, the Fittoa Region, roughly 80 years in the past. The Miko's hope was that this would allow Shizuka to set things up to where Akito would not have to die. Unfortunately, the world itself fought back against the Miko's attempt to alter fate, and thus nothing happened initially. However, the Miko's attempt to summon someone from another world opened up a rift in space from which the soul of a recently deceased individual emerged. This person would end up becoming Rudeus Greyrat.

Due to Rudeus not being from this world, the world's resistance to the Miko's power began to wane as the boy grew and began to influence the fates of those around him. As a result, the void eventually became visible to the naked eye in the form of the floating red orb. Eventually, the world could no longer hold it back and the rift fulfilled its purpose by successfully summoning Nanahoshi Shizuka into the world, causing the Teleport Incident in the process.

Teleport Incident Manifesting
In K417, huge amounts of mana gather around the orb and looking like a storm with eight eyes. Orsted and Kishirika Kishirisu senses the gathering of mana and mobilizes to find the source. Perugius Dola aboard his Sky Castle notices the mana resembles the light of summoning and considers the possibility that someone could be seeking to undo the seal on Laplace. Perugius then commands Almanfi to investigate the source of the mana and kill any suspicious persons on sight. At this time, Rudeus, Eris and Ghislaine are outside of Roa to test out his new staff, Aqua Heartia that Rudeus received on his tenth birthday from Eris the day before. Almanfi attacks them but Ghislaine fights him briefly and assures him that they have nothing to do with the incident. As the magic activates, Almanfi teleports out of the area then a pillar of light lands and expands at high speed, enveloping anyone it touches and teleports them randomly all over the world.

Casualties
Due to the Teleport Incident massively affecting the Fittoa Region, the definite number of casualties and missing are nearly impossible to account for. The Refugee Camp of the Fittoa Region has a list of missing and dead while adventurers and former adventurers alike search for the missing and coordinating with adventurer's guilds in the continent.

 * Rudeus, Syphiette and Nanahoshi begins research to uncover the truth of the incident as this has never happened before according to Orsted.
 * Nanahoshi theorizes that Hitogami is involved with the red orb's appearance when Rudeus was 5 years old during the time he grew closer to Roxy and Sylphiette and the incident itself happening a day before Rudeus is about to sleep with Eris.
 * Nanahoshi also theorizes that her being summoned and Rudeus' existence is to set in motion the events for the future where Rudeus' descendants will ally with Orsted to kill Hitogami and suggests that Rudeus consult with Orsted.
 * Despite being protected by a strong fate, the situation of the people affecting Ariel on becoming the Asura Kingdom's queen has been altered from Orsted's knowledge of the original history such as: :
 * Derrick Redbat who is supposed to persuade Perugius on backing Ariel to become queen, dies while protecting Ariel from a terminate boar and is succeeded by Syphiette.
 * Luke Notos Greyrat marrying Eris and both becoming Ariel's bodyguards who will protect her from numerous assassination attempts and eventually becoming queen does not occur.
 * With Eris being Ariel's bodyguard, Sauros and Philip are suppose to join Ariel's faction but this does not occur due to their deaths.
 * After being saved by Ariel, Tristina Purplehorse is supposed to testify as a live witness against Darius Silva Ganius on being kidnapped then forced to become his sex slave and causing his downfall goes missing.

Trivia

 * Despite the random nature of the teleportation; Rudeus and Eris, Paul and Norn, Lilia and Aisha were teleported to the same place together because they are in physical contact with each other before they are teleported.
