The Eiram and E'ronoh War, also known as the Eiram–E'ronoh war, was a conflict fought between the planets Eiram and E'ronoh. The conflict involved several wars between the two planets, which was why it was also referred to as the Forever War. The latest incarnation of the war was fought between 387 BBY and 382 BBY. The Spiral-class Viz-Core Eviscerator starfighter model saw action during the war. The peoples of Eiram and E'ronoh would not settle their differences, entering into a cold war, until the aftermath of the Eiram–E'ronoh crisis.
The Monarch of E'ronoh doubled down on the war again after his son Niko A'lbaran died on a diplomatic mission to Eiram. The Monarch thought that his son was killed by the the queen of Eiram which was not true as his son had drowned in a tragic accident. Also the E'roni's believed that Eiram stole their colony on the Timekeeper Moon which further increased the tension between the planets. The Battle of Salamento Bridge was fought at one point.
Because important trade routes went through the Eiram system, several worlds dependent on imported food were beginning to starve as the war made the trade routes in the Koradin sector, including the Lipsec Run, unusable. The planets of Sump and Shuraden requested aid from the Republic for this exact reason. The Republic conducted extensive remapping and cleared the hyperlanes of pirates who tried to collect their spoils of war twice to reestablish a lifeline for the starving systems again.
The war also caused one of E'ronoh's few allies, Merokia, to cut ties with E'ronoh and not fulfill their promise of relief and decreased the off-planet marble contracts of E'ronoh drastically. The Path of the Open Hand arrived on E'ronoh at least and secured new followers from young citizens who wanted to avoid the draft.
Even though the war never reached Eiram's capital in the form of fighting, surrounding towns were attacked which eroded the infrastructure of Erasmus. Eiram's population was hit hard by the effects of the war as food and water had become scarce goods. Additionally the environment suffered heavily during wartime. The many beaches of Eiram were often stained with oil and fuel that leaked from downed ships. Surrounding greenery was burned from explosions and dwellings were in disrepair.
Out of desperation Eiram's queen Adrialla made a bargain with The Mother for food, fuel and medical supplies. When she did not uphold her end of the bargain though, The Mother sent one of her Children to threaten her into fulfilling her promise.
Five years after the war reignited, a new attempt for a ceasefire was made. Though the The Mother tasked one of her Children, Serrena, to manipulate one of Thylefire Squadron's starfighters which was supposed to be flown by Xiri A'lbaran in hope of breaking the ceasefire and prolonging the war between the planets. Although the sabotage operation was successful and caused a skirmish between Eirami and E'roni forces, the ceasefire ultimately held. However, the Path's interference with the effort to sign the treaty on the neutral moon of Jedha resulted in the conflict exploding into active warfare again with the Battle of Jedha. In learning the Path of the Open Hand's role in engineering the war, which it hoped to use to create chaos it would thrive within, the peoples of Eiram and E'ronoh united against their common foe and entered the Battle of Dalna together.
