Four Horsemen Incident

The New Four Horseman Incident was the name given to the numerous terrorist attacks in Divine Levianta perpetrated by Neo Apocalypse in an attempt to overthrow the Levin Church. Partially instigated by the suppression of radical heretics by the dominant Levia sect, the incident pushed Levianta to call for international help in putting down the growing crisis.

Origins
During the turn of the 6th century EC, three members of the Meta sect in Divine Levianta rebelled violently against the Levin Church in an attempt to end the longstanding oppression the cult faction faced from the dominant Levia sect. Over time, the diehard reformers repeatedly clashed with the Church over the issue, though failing to successfully change the status quo.

In EC 508, one of the candidates for becoming a leader of the Church, Mikhail Asayev, came in contact with the sorceress Abyss I.R. Falling under the influence of the Twin Swords of Levianta, Mikhael's jealousy of his current position compared to his constituents pushed him to adopt more radical policies. Shortly after, he contacted the radicals of the Meta sect and formed a political association with them to overthrow the Levin Church: Neo Apocalypse.

Widespread Terrorism
Throughout the year, Neo Apocalypse staged numerous terrorist attacks within Levianta and caused growing damage against the Church. Later that year, the Church asked for the cooperation neighboring nations in Evillious to help quell the terror strikes. The Kingdom of Elphegort immediately rejected the proposal for aid; while the Kingdom of Marlon hesitated to interfere in the conflict, its largely independent Lucifenia territory agreed to send a single detachment of troops.

Afterwards, Lucifenia deployed a company led by Riliane Mouchet to Levianta. During the conflict there, Germaine Avadonia and Chartette Langley arrived in Levianta whilst traveling through the region. Soon after, Abyss I.R. confronted Germaine and the two battled, resulting in Germaine's defeat. Abyss then took control of Germaine's body. Around that same time, Elluka Clockworker and her apprentice, Gumillia, arrived and became involved in the conflict.

Neo Apocalypse then began expanding their attacks into wide-scale destruction to cause the collapse of the Church. At some point during the conflict, Abyss managed to take the Glass of Conchita from Elluka. After Riliane's troops arrived to help stem the conflict, the commander came across Abyss I.R. and battle the sorceress. Defeated by the soldier, Abyss I.R. fled without the Twin Swords of Levianta and the vessel was soon after acquired by Chartette. Neo Apocalypse was then eventually subverted.

Aftermath
After the end of the conflict, Chartette traveled East with the Twin Swords until she reached Snakeland. Hoping to keep the vessel out of the mage's hands, she settled in Enbizaka and then reforged the blades as two pairs of scissors. Elluka and Gumillia continued on their journey afterward in pursuit of Abyss I.R. and the remaining vessels of sin she carried. The Levia sect continued to assert its dominance afterward, suppressing any other heretical sects within the Church.

Civilian Perception
Neo Apocalypse's terror attacks spread concern among the Levin Church and its followers in Levianta, prompting their call for aid from other nations. Levianta's longtime ally, Elphegort, outright rejected helping them in the wake of Levianta's failure to provide aid during the Green Hunting. The Kingdom of Marlon was also hesistant to become involved in the affair while attempting to slowly set up Lucifenia as an independent nation. Although eventually receiving aid from Lucifenia, they sent the up only the minimum of a single detachments of soldiers for support, rather than a larger army.

Neo Apocalypse's motives for wanting reform from the Levia sect's oppression was recognized by the public, though their radical measures were condemned as well. Similarly, the Meta sect's connection to Mikhail was considered petty envy against the Church, with his actions simply being in the interest of advancing his position in the world. The organization's name and actions were assumed to be inspired after Pale Noël and his Apocalypse organization during the Magic Kingdom Levianta's reign.

Conceptualization and Origin

 * The "Four Horsemen" members the event is named after are based on the Four Horsemen depicted in the biblical Book of Revelation, acting as signs of conquest, war, famine, pestilence and death to foretell the second coming of Christ.
 * The term apocalypse is derived from Greek, meaning "uncovering" or "revealing" and is used in contemporary times to refer to a great change or destruction, often the end of the world.
 * The term "neo" is derived from the Greek word neos, which means "young, fresh, new or recent".
