A conflict that started 300 years ago originally as a civil war between Cherembryl Empire, and its territory known as Pashbon. Pashbon grew quickly once it gained its independence, and gained territories and allies from the east. Using this strength it was able to contain the aggression of Cherembryl, and eventually fought them to a standstill. This is where the first phase of the war ends.
The second phase begins as a border skirmish between Pashbon and some minor tribal hobgoblins. Pahsbon had used the breathing room of the stalemate with Cherembryl to embark on an ambitious civil works project, one that would remake their dry plateau of their central territory into a large inland lake and bountiful fields of rice. This would cause a minor famine in the short term, but long term would increase yields tenfold. During the worst part this minor famine the hobgoblins invaded in force. Unable to keep their army in the field due to the famine, the Pashbon kingdom fell, and the hobgoblins to their amazement came into possession a bountiful and powerful kingdom to rule. Using the momentum of the population boom of newly opened land and the martial expertise of the hobgoblins the Pashbon Empire as it was now known was able to break Cherembryl, causing its nearly total destruction.
The Third Phase was also its shortest. A Crusade was called in the west, and the 7 Kingdoms and Kadesh turned back the tide. The Pashbon empire then fell into its own civil war, breaking apart into its core territory and the hoblgoblin homeland. The House of Vec was victorious in the civil war, and renamed their empire after themselves. Due to war exhaustion, the need to consolidate power, and potentially richer pickings to the east, The Empire of Vec signed peace treaty with Cherembryl, one that has held for 50 years, thus ending the Long War.
