No, we are actually playing in the final days of Amun. You see, if you read on in The Lost Patriarch, that actually takes place 1,000 years after the fall of Amun. I'll explain this more for everyone:
The Goblins of Skelandgrief border the lands of Amun, they are the main hostility towards the Amunians. It is recorded in history that eventually, the Goblins began a massive invasion, and began taking Amun. Eventually, they pushed their ways to the very borders of St. Pox, where Patriarch Naguno and the Dragonknights rode out for a final stand. They fought a vicious battle, but the Goblin Chieftain had made a pact with Kairm, the God of Death, to help him defeat Amun in exchange for his soul and the souls of all his tribesmen. He placed a vile curse on the land, corrupting all forces of good. This wearied and greatly weakened the Dragonknights. Eventually, they made it to the Warhall, where Naguno and 3 Dragonknights remained. But after a terrible battle, the Chieftain killed Naguno, and his Goblins ripped apart the last forces. St. Pox was sacked, and that is when Amun fell.
Also, no women have ever entered the Academy not because of policy, but that the extreme weight of the Armor, the Lances, and the power of the Dragons is normally too much for the petite Amunian women. Most highly skilled female soldiers serve in the Dragon-Stalkers, the elite Assassin corp of the Kingdom.
