The Opal Kingdom, the name of the Kingdom located in the middle of the Gem Regions is one of the most famous places that you can find in this wide world, from adventure guilds to firms or even famous restaurants, ... all of them surrounding the Opal Kingdom.

The reason for that is in a story a long, long time ago.

100 years ago, the star from the sky that we always used to see, became monsters and started to eliminate humanity.

Being attacked so suddenly, all humanity can do is stand here and do nothing because they can't fight back, they are too small in front of the monsters.

At that time a hope from nowhere appears, he is the first Prince of Opal Kingdom, and with him is a myth beast Dragon.

No one knows how he can contact or make a contract with the dragon, but with the dragon's help, humanity's success brings back their hope at the edge of death.

After the battle pass, the hero of the citizen, Prince of Opal Kingdom disappears like he never exists.

In order to tribute to his glory and prepare if the stars to fall again, the king of Opal Kingdom creates an academy that teaches all elite persons in the Kingdom and from everywhere in the world in order to help their talents grow more than ever for the future-That the start of the Opal Academy.

10 Years after the war ended, the Princess of the Opal Kingdom who swear to continue her brother's pride, success in finding that humans can also use magic like other species like elf and drawf or spirits in this world after following her brother's path, but before she received her rewards, like her older brother she also vanished like never exists.

The only thing she left is a letter for her family:

"Dear father,

I'm really shameful that I must leave before giving you a farewell.

But believe me, we will meet again when the time comes.

Fate is sometimes cruel, but humanity must overcome it.

Please father, you must keep the academy from growing, and we will meet again I promise.

Farewell Father."

That is a sad story, sudden threats, sudden hope and all disappear in the end.

But according to history, The King and his last child, the second Prince, keep contributing the best to the academy.

They want to protect what their family love, and that is the reason why after 100 years, the Opal Kingdom with the Opal Academy lies in its territories became one of the strongest lands in the world.

After 100 years, the clock of fate starts to move again.
