The Tharrisian's quickly overwhelmed the Foreleni border and its guard, diving deep into their territory before a response could be formed. By the time a response
did appear it was too little too late against the legions of Tharrisia. Instead of defense, the Foreleni army soon found itself in a desperate rear guard action as loyal soldiers and forces retreated to the capital of
Aeraguard. At the same time, dozens of cities and regions simply declared for Tharrisia, seeing which way the wind was blowing.
Sernita Verro and her legions found themselves at the gates of Aeraguard within two months, and prepped for a siege. Tharrisian's were experts in Fallen City sieges so the fall of Aeraguard was considered to be an easy task. This proved to not be the case as the Foreleni put up a dogged fight that lasted seasons. The big factor turned out to be necromancy, as the ruling Dragon Council of Forelenium had no problem authorizing its mages and wizards to raise the dead, Foreleni and Tharrisia alike, to swell its ranks. The undead needed no food, no morale, and no equipment, they could be sent, wave after wave, at the Tharrisian's to slow them down. When the Tharrisian's were tired, actual Foreleni soldiers could strike.
During the siege, the 16th Legion peeled off and headed into
The Nation of Ghosts of ghosts, allegedly to annex it as well as it was a "lawless and stateless" region, but more specifically to find the Aithero Monopati for Aenophentari.
In the end though, supported by new siege cannons from
Jarak, the walls of
Aeraguard were breached and the city fell. The legions began the process of conquest consolidation, while several legions prepared to head east to support the 16th.
This course of action was interrupted by a sudden declaration of war by
Aurelia,
Embrel,
Heldir,
Straka and later
Atresa. Egged on by
The Wayfarers, these nations united in alliance against Tharrisia. Allegedly to stop the blatant land grabbing, but in reality to stop whatever plan Aenophentari had for the mystical Aithero Monopati.
Tharrisia suddenly found itself pressured on multiple fronts. The original intention to take a lot of the conquering legions east to
The Nation of Ghosts was halted, as the legions were split up.
Two legions, led by Sernita Verro, headed east to support the 16th as planned. Meanwhile two legions headed west, to the Foreleni border with Embrel, and three legions headed south to the Poutonese border with Heldir. Back home in Tharrisia proper, the home defense legions and auxiliaries reinforced the border Tharrisia shared with both Aurelia and Embrel.
The first battle in the war was actually the conclusion of
The Dragonborn Civil War, which is somewhat tied to the events of the Tharrisian War due to the manipulations of Aenophentari.
While the various armies of the nations marched to war, an unheard of amount of airships gathered around
Starmont Allod and loaded up with soldiers from every allied nation to head east, to
The Nation of Ghosts to halt Aenophentari and the 16th legion.
The Wayfarers headed first, discovering both the long lost Tomb of the Eternal Queen, as well as an ongoing battle between Idiomar's Reformers against the 16th Legion. Upon their arrival they dived deep into the Tomb, killing Loukas Pardontis and another of Aenophentari's lieutenants.
Around this time, a squadron of
Virnosian warships, led by Commodore Pleri and
Gareth Pancem arrived at the shore where the battle between Idiomars Reformers and the Scout Auxiliary of the 16th was ongoing. They soon unloaded marines,
Green Guard, and other soldiers to reinforce the reformers and quickly turned the 16th away. Not too long after, the massive airfleet from Starmont arrived.
Concurrently with the skirmish in the Nation of Ghosts, a large battle squadron of
Ithalin ships arrived to the recently conquered
Gallows Isle and launched a raid against one of the Tharrisian strongholds on the island, destroying an arcane crystal that had been blocking sending magic throughout Kalin. Their fleet also arrived off the coast of Heldir, driving away and destroying the last of the pirates from
The Conquest of the Gallows Isle that had been harassing the Heldir coastline.
With the arrival of the transport air-fleet to the Nation of Ghosts battle became inevitable. To bring down Aenophentari as fast as possible,
The Wayfarers planned to take a small force and travel to the City of the Dead, where the Aithero Monopati was thought to be, while the rest of the allied army took on Tharrisia and its auxiliaries. This battle would become known as The
Battle of 14 Nations and is generally accepted to be one of the bloodiest and most horrific battles up to that point in the Second Age.
Concurrently with the Battle of 14 Nations there was also the
Battle of 14 Nations in
Starmont Allod, which was a decisive Embrel-Aurelian victory, as well as a group of skirmishes along the Heldir border now known as the Battle of Six Pinpricks.
While The Battle of 14 Nations was ultimately a tactical draw, the Wayfarers succeeded in killing Aenophentari and closing off the Aithero Monopati. The 16th Legion and its reinforcements soon withdrew from the Nation, seeing no purpose in wasting the manpower any further.
The allied army soon returned to their constituent nations, and
The Wayfarers returned back to Starmont Allod in victory.
After the victory celebration the war continued. Within a month the Ithali and Tharrisian ships would have their first major naval battle off the coast of Heldir in the Battle of Two Winds ending in a draw (and would also be the last major engagement by Ithali forces during the war), while Heldir would suffer a disastrous defeat during the Battle of Bragan Hill. Two months after the defeat of Aenophentari the Tharrisians would attempt a piercing invasion of Embrel, nearly succeeding to drive towards the fallen city itself until Aurelian pressure on the Tharrisian border forced a retreat.
Following these three major battles most of the fighting would devolve into skirmishes and overland campaigns instead of set-piece battles. Work would be done in the shadows though, as
Jayllin Tano and
Evoda Vitri, along with some help from
The Green Guard, Aurelian Spy Networks, and the Bronze
Kobolds of Tharrisia, would begin to spread the word that Sernita Verro was a servant of Aenophentari and owed all her success to him. They would also help Octavian Ghiacciato,
Octavia Ghiacciato's father, in roundabout ways win support for his rising Rinascita party.
The political situation in Tharrisia would hit critical mass during the Autumn of 756, when Sernita Verro finally lost control of the Senatus and was thrown from power. This was quickly followed up with a political purge that saw most of her still loyal supporters arrested (and often times executed) while she herself vanished and went on the run. This was quickly followed by requests from Tharrisia for peace discussions.
The peace discussions took place on
Olbern, a neutral state, and took nearly a full season of back and forth between the various nations. Tharrisia wanted to keep all of its conquests, including those made in
Heldir and parts of
The Nation of Ghosts, whereas many allied nations wanted Tharrisia pushed back to its original territory, with certain parties even demanding Tharrisia give up The Gallows Isle and even
Singlar.
In the end though, to make peace, a compromise was reached, land partitioned, and the brief but bloody war ended.
