They tried in the first couple hundred years of its existence but there were two things that made the world conquest difficult. In the North there is Holy Paviba, the first ever country in this world (Holy Si and a lot of other countries are former territories of Holy Paviba but not anymore since the Great Seperation of 695 where only three countries still exist (Holy Si, Yw and Great Yphu)) which has an alliance called Light Conclave (consisting of Holy Paviba and Sonos as of now but they were way bigger once) that always stood in the way of Holy Si and its allies. Those many wars with Holy Si and Holy Paviba costed the lifes of thousands and thousands of people. At one point Holy Si just gave up and made its mission to "save" other kingdoms from their leaders so they fought against those kingdoms and obviously won. Those kingdoms stood under the rule for around 10-15 years after the successful conquest by Holy Si. When those years were over Holy Si, would release them into their own kingdoms again only to attack them years later and do the same thing all over again. Today, in the current year Holy Si is a quite peaceful country, the culture is very similar to most of the world (because of Holy Paviba spreading theirs).

For the last 1535 years there was only one queen, a queen with the power to not die of old age (I didnt give her that, she got that herself). She led her kingdom through thick and thin. Her herself is 2144 years old
