1)13 Year Great War
Almost 200 years ago around 1679 AD King Hektic directly attacked Sagacia formerly known as Sagalle. On defence Aegles also declared war. after a bloody battle of 13 years Aegles were forced to admit defeat. But these battle took a lot of toll on both sides which actually brought a change of heart in King Hektic. This war actually changed the Prism Kingdom's law and order which now prevails any ruling individual from genocide. Plus the structure of army changed from aggressive to passive(From killing people to protecting people). This war also soured the relation between Human and Aegle.
2)Formation of G.A.M.P
After 3 years of 13 Year War King Hektic decided to establish an organization to keep peace across world. To do that he came in agreement with Wyords and Treefolks and established G.A.M.P(Global Association for maintaining peace) in 1682 AD. It was later joined by Dune roamers and Aegle respectively in 1683 AD and 1697 AD.
Currently there are 5 forces in this organization- Humans, Aegles, Wyords, Treefolks, Dune roamers.
Every year an annual G.A.M.P meeting is conducted to discuss upon various topics like- yearly resolutions.
3)Age of Science and Magic
In this time(Approximately 1687- 1769) Humans and Aegles started their technological and magical advancements separately. In this race Aegles(Reagalle livers) went ahead of Humans. Still they always kept thamselves passive as they taken the policy of non violence like Prism Kingdom. Though Regalle livers never contacted human but some Sagaciaians later around 1686 made amends with Humans sharing their knowledge about magic and Humans sharing their knowledge about science to Sagacians.
