The Panthalassa War was a global conflict on Coracan and was also the first war to be fought on an extraterrestrial body, Serulus.
No major wars had taken place in 69 years. Since the Twelve Years War of 4170-4182, two or three generations had grown up without knowing war.
During and after the worldwide depression of 4195-4210, Eupatriot ideology began to form and several countries whose governments had become Eupatriot allied together. Fearing the rise of Eupatriotism, countries aligned as anti-Eupatriot formed alliances that would later join to be the Coalition forces in the Panthalassa War.

Starting in 4235, a space race began, fostering great competition between the military alliances that would later become the Coalition and Eupatriot groups. When a Baraghovian man, Captain Rurik Kaman of the Baroghovian Space Agency became the first to land on Serulus on the 1 May 4249, tensions flared. Accusations flew that the Eupatriots had sabotaged the Coalition efforts.
Course of the War
War breaks out in Eyo (4251)
The Kjhelic Army invaded east first, with the Laurentine Empire. When neutral Seryan was invaded, Cassavel issued an ultimatum for the Kjhelic army to withdraw. When the ultimatum lapsed, Cassavel declared war on Kjhelde and all her allies. The Coalition planned to meet the Kjhelic forces head-on in the west of the country and in Seryan and attack the Kjhelic heartlands northwards from Dallinae.
Cassavellian war planners had long thought that the key to victory in a war with Kjhelde would be to attack it from the west and south (from Dallinae) simultaneously. Unbeknownst to them, the Eupatriots had secretly brought previously Coalition bloc countries around Cassavel into the Eupatriot fold. This meant that Dallinae would be attacked from all sides, neutralising a Coalition invasion from the south. The main part of the Eupatriot plan here was to cross through Seryan and smash Cassavel's weakly defended northern border with Eregos
Westwards invasion of Eyo (4251-52)
Beginning on 7 Apar, this plan was put into action. In the beginning, Coalition forces made reasonable gains into Kjhelic territory. This would prove to be fatal for Cassavel. As Cassavellian forces moved further away from their capital and deeper into Kjhelic lands, Eupatriot forces initiated an attack from Eregos and another into the east of Dallinae. These attacks took vast swathes of land with little resistance, threatening Sipigrangor and flanking huge portions of the Cassavellian army. As the Coalition forces retreated to defend Cassavel, the Eupatriot armies in the south captured Dallinae and made a huge offensive to meet the main Coalition force.
Most of the Coalition forces were surrounded and had to surrender. The rest fled into Bandon to set up new defences. These efforts failed, however, and Coalition forces on Eyo retreated west or south to defend the crucial city-state of Darana. The Seige of Darana lasted over a year, but with the Cassavellian Navy completely incapacitated and the Bandonian Navy having lost most of its ships east of the Straights of Kibbar, the Straights fell under the control of the Eupatriots.
Five years of stalemate followed with little to no movement on all fronts. The war descended into one of attrition, the resources and industrial capacities of the factions were pitted against each other.
Project Toba enacted (4257)

Beginning on the 15 Charu 4254, a secret project began between the Coallied nations. Project Toba. Their mission: to create a new kind of weapon, one that could release the enormous power of the atom predicted by physics. Over the years, more and more scientists, intellectuals and specialists from Eupatriot nations (especially those considered 'undesirable'). It was this transfer of brains that made the Coalition atom bomb project far ahead of any Eupatriot efforts. After a test on 45 Arum 4256, production of enough A-bombs to incapacitate the main Eupatriot nations.
In Operation Kurut, colloquially known as the Day of Devastation, the last serious air forces that the Coalition still had flew over the major Eupatriot capitals in imitation of air raids. Millions of people and huge sections of Eupatriot leadership disintegrated in a matter of hours.
Coaltion closes in (4257-58)
In Operation Stucco, all the resources and manpower that the Coalition had left were concentrated on taking the Eupatriot capitals. They expected heavy resistance, but most Eupatriot forces had had enough and often surrendered without a fight. Also, as their central command systems and logistical systems no longer functioned, orders, equipment and even food were in short supply for the Eupatriots.
Final Coalition victory (4258)
After the surrender of what was left of the Eupatriot governments, Coalition forces had to spend several more months defeating guerilla groups that continued to fight. The end of the war is considered to have taken place on 11 Ser 4258, with the surrender of Mankato, a Baraghovian who continued to lead guerrilla forces but also was head of state. Since Baraghovia had not officially surrendered and Mankato continued to control territory in an organised fashion, this is the most universally accepted end date of the Panthalassa War.
