Celestia was a country situated near the equator - with a hot and humid climate. There are huge greeneries at the border of this country.

People even refer Celestia as an island, since it is covered by Oceans and Seas.

Now lets us zoom into the coordinates of the country

Latitudinal extent - 1°23'N to 7°6'N
Longitudinal extent - 79°37'E to 85°53'E

The country was ruled by a dictator - Orion. He had a personal rivalry towards the group of people known as the 'Zodiac'. Therefore he wanted to eliminate this particular group.

He first took away all the advantages and rights from them. They are excluded from the majority and forced to stay in villages situated at the border.

Marriage between any citizen belonging to majority group and people of zodiac group was made illegal.

His next intention is eliminate them by genocide and war. His actions and ideas alarmed the 'Zodiac'. And unfortunately a war was declared and it killed millions of people of the Zodiac group. People from Zodiac started violent protest, war and rebels over many years which finally  led to the execution of Orion and a part of the country became independent, now named as 'Astro'.

But how all this happen, what did the war cost?, what did the people of zodiac do? What damage it caused? How did neighbour countries react?

To know all this, we need to zoom into the lives of the legend, who took part into the freedom struggle.
