The name refers to a conflict between the La Plancha Sovereignty and the Ísparus Migration, an expeditionary and conquest force primarily made of Swablu, Deino and other dragons migrating across some continents and using Suocé as a temporary stop. The conflict started sometime ca. 3710 PE^{(~23 before Gen1)} , when the migration force started placing permanent dens in the southern Suocé cordillera, and ended around early 3735 PE^{(~2 after Gen1)} .

The origins of the conflict lie in the fact that, up until the 37th century, a number of Pokémon species such as Swablu and Deino would migrate eastwards from the Poké!Oceania continents and out to the region of Ásfiri (more or less Poké!Namibia), using the continent Suocé is located in as a springboard. However leading to ~3710, changes building up in the population of the species and the world's weather, forced the yearly migrations to set up more permanent nests in the central cordillera of Suocé, in the mountains directly south of the district of Ísparus and following to the west down to the district of Cholcone. With the establishment of permanent dens, came the need to both establish a territory, and the need of the new inhabitants to secure food.

By the time of 3712 PE^{(~21 before Gen1)} , the establishment of breeding dens put the dragons into more direct confrontation with the surrounding grounds, with the speciality hunters Fuuma and Seishirō sent to oversee raids on three surrounding territories.

The Claim decided to not expand south to the Cadrícean Widefields Sovereignty seeing as it was defended both by humans and by a Deer Trio; they could not expand to the western coast either due to the presence of the Shrine of Magic and the fact that the area was recurrently guarded by high-level Trainers (such as Léos Ward and Nadia Shepard). Instead, they turned to the plateau hosting the La Plancha Sovereignty to the north: an elevated and isolated biome rich in bug and mammalian Pokémon as well as other sources of sustenance that the dragons could prey upon, without the guarding eyes of humans or Legendary Pokémon.

By the time of 3715 PE^{(~18 before Gen1)} , dragon raids on the southern and eastern edges of La Plancha became more frequent, as Swablu and Deino would fly in in flocks and take their prey among the local population of Pokémon such as Spinarak, Skorupi, Nidoran and Zigzagoon that did not have effective defenses against them. However, against orders by Fuuma that the priority was to build up nests so that the dragons could jump from continent to continent in droves, the Swablu population persisted in continued attacks upon La Plancha.

Over time the lead dragons became worried that their presence would be unwelcome by the Shrine of Magic and other surrounding factions that could observe the events in La Plancha; they feared that it would become necessary to amass an invasion force and land a definitive hit on the Sovereignty to conquer and annex it, as the feeding dragons marched deeper and deeper into the grounds of the Spinarak and Nidoran colonies and it would surely not be long before humans would intervene into the conflict.

To that effect, Elder Dragon Rhanzikik migrated over from Omixence and installed himself in the central cordillera nests at some time near 3727 PE^{(~6 before Gen1)} , and started organizing the migrating dragons into two camps: a conveyor group tasked with feeding, equipping and flying migrants out of the cordillera and off to Ásfiri, and a conquest force tasked with regular invasions to the outer layers of La Plancha to prevent them from ever building up a counterattack.

By around 3729 PE^{(~4 before Gen1)} , the situation in La Plancha had degraded severely. Swablu raids were so frequent that they would basically show up on any given morning to feast upon the Nidoran population as breakfast ( Tricks of the Love Fast ).

Confrontations escalated with the dragons nearing the breeding grounds of the Nidoran colony until some time around 3731 PE^{(~2 before Gen1)} . Inka, a formerly trained Nidoqueen that had recently attained her evolution in the caves of La Plancha, emerged and took over command of the Nidoran colony from the breeding cabal. She quickly went on to lead counterattacks against the raiding Swablu and built up a force strong enough to take over leadership of the Sovereignty.

Using the teachings from her time as the Starter of (by then Champion) Machalí sol Linaros, Inka started a process of brute militarization of the Nidoran colony and sought attachments from the Skorupi and Zangoose populations. Gathering some other formerly trained Pokémon to her cause, they started training the wild Pokémon around to resist and counter Swablu and Deino raids ( “Serebii Character Interviews” N/A? ).

Inka's Champion-level experience and the alliance with other formerly trained Pokémon in the area and other species soon escalated the resistance in the Mesa, allowing the various species to counter dragon landings and even pursue their attackers back to the Cholcone Valley, resulting in deaths over human territory. Rhanzikik issued a strong response, sending expeditions spearheaded by Sotsinak and Fuuma to burn down the eastern nests in the Mesa used by various bug and normal type Pokémon, hoping to cut off about one third of their free feeding area.

After one such raids in 3734 PE^{(~1 after Gen1)} , Inka, suffering the loss of a litter of her offspring and the apparent loss of her firstborn Maekrite, gathered her forces for a vengeance counteroffensive using to her advantage the rest time the Swablu needed after their landing in the cordillera. Inka and her mate Baluarkos spearheaded a specially crafted force that would attack the surroundings of the dragon nests, drawing them out into mountaingrounds where Inka could deal with them. By an accident of multiversal manipulation, that particular raid was observed by extradimensional traveller Jason Rykker (Pokémon: Legends Sinjoh).

In the confrontation that ensued, the Monarch Couples Inka brought, as well as other few Pokémon, managed to pick the precise location of the dragon nests and dig into them to wreck them, destroying tens of dragon eggs in the process. Inka and Rhanzikik faced each other, with the Nidoqueen barely coming out alive; but the elder dragon did not, and the lawgiver and second-in-command Seishirō, witness of the event and second-in-command, denounced the Nidoqueen as a Dov Volkaal (“horror of dragonkind”) and mandated the evacuation of the foothills of the Cholcone cordillera.

With the loss of Rhanzikik and the damage suffered by the Cholcone grounds guarded by humans, hostilities dialed back significantly, with the dragons deciding to now focus on completing Rhansikik's original plan of a “conveyor” service. Around 3736 PE^{(~3 after Gen1)} the dragons decided to establish a takeoff point in the cordillera and a migration station in the beaches south of Pradeimie, which had been vacated by other warring Pokémon. With this, the frequency of the raids over La Plancha dropped significantly down to what local Pokémon considered “normal” predation patterns, and the conflict between both parties was considered largely over.

By that time, Inka had already settled down from her role as the regentess of La Plancha and retired from active life, both trained and as a wild, and rule of the La Plancha Sovereignty had been passed down to the local Zigzagoon communities. Maekrite, the kitten she had thought lost, went on to become Machalí sol Linaros's third Starter sometime around 3736 PE^{(~3 after Gen1)} when Machalí was summoned to assist the logistics of the Gold Conference.

Rhanzikik's death left a position technically open within the Seven Star-Claws council, as the Elder Dragon had actually been retired due to health issues already before travelling to Ísparus. The slot was later given to Kalosian dragoness Yanoyâfa at some point in time around 3742 PE^{(~9 after Gen1)} , and she recruited both Fuuma and Seishirō into her ranks.
