A Song of Hope & Sacrifice (ASOIAF/GOT)

It is the year of 1492 King Casimir IV Jagiellon has just died,his son Augustine Jagiellon is going to be crowned king of the Polish Lithuanian commonwealth.Many were mourning the passing of the old king,becouse under his leadership the commonwealth defeated the teutonic knights and recovered pomerania and gained east prussia also becouse of him poland narrowed the distance seperating it from the western europe technologicly.For the next few years poland should have been at peace,but something unexpected happened the polish lithuanian commonwealth completely disappeared from the europe. And it appeared in a completely different world. (I took my inspiration from Chill_ean_Guy) (english is not my native language so there will be mistakes,its also my first fanfic) (also some things arent historically accurate,for example the commonwealth wasn't formed yet and the next king should have been john albert and there won't be a sejm(it's an nobility thing and it really limited the power of the king)the commonwealth will be a autocratic monarchy) (I don't own asoiaf or game of thrones they belong to George rr Martin)
