"Hydor City, according to myth and legends, the city sank to the bottom of the Stryk Ocean long ago."

Located at the north of the country Venasca, lies the Stryk Ocean. The Stryk Ocean is a vast and is the widest ocean, it is where the Hydor City is said to sank.

Venasca was known for it's fishing industry. Tons and piles of fishes were fished everyday. It is called as the "Blue City", but no one know that a nightmare is about to befall upon the city.

One day came, fishermen who set sail on the ocean never came back. The skies turned dark and the tides became wilder day by day.

The people panicked. The Elders of the town were alarmed, for the prophecy is happening.

"When danger befalls upon the City in the bottom of the sea, the waters will be wilder. Storms will rage on. Destruction of Venasca is assured."

Now, the fate of the country of Venasca is in the hands of Thalassa Bluestone and her friends.
