The Last War was a conflict that raged between Aundair, Breland, Cyre, Thrane, and Karrnath. Its purpose was to reunite the Kingdom of Galifar after the conflict over succession that started upon the death of King Jarot in 894 YK. The conflict lasted over a century and ended with the signing of the Treaty of Thronehold in 996 YK.
As King Jarot of Galifar approached old age, questions about the succession of his throne ran rampant. Although by tradition his eldest scion, Princess Mishann of Cyre was to claim the throne, others doubted her ability to rule. Prince Thalin of Thrane felt he was far more fit to rule instead. However, on the king's deathbed in 894 YK, he gave Mishann his blessings and bade Prince Wrogar of Aundair to honor his decision.
At the funeral shortly after, Mishann discussed the details of her coronation with her siblings, but they turned a deaf ear to her words. Indeed, they personally threatened to send their soldiers to Thronehold to prevent any such action. Only her brother Wrogar remained allied to Cyre, since he was bound by honor. Later in the year 894 YK, hostilities commenced. Alliances were formed, shifted, and were broken over the course of the war. Virtually no part of the continent was unaffected.
The Treaty of Thronehold was signed in 996 YK, two years after the Mourning destroyed Cyre. The treaty effectively put an end to the conflict while recognizing twelve of the fifteen new nations that had come into existence during the Last War.
Although the signatories abide by the treaty, many feel that the current peace will only give way to more warfare. Until one nation defeats the others and claims the throne of the ancient Kingdom of Galifar, many believe there will never be a true and lasting peace.
Behind the Scenes
The Last War seems to be partially based on the Hundred Years' War, including its origin as a war of succession denying a female heir, introduction of new military technology, and duration of around a hundred years; and the First World War in its new technology, inconclusive outcome, and similarly naïve name ("The War to End All Wars" and "The Last War").
