Vortex Island is a very special place. It was originally located in the northeastern part of the beast country where it meets Spiral Bay, where there is a long-term interaction between the meandering realm and the magnetic pole of the earth's boundary, and the landform and ocean currents are very strange, and it is called the "Lost Land".

Further east of Vortex Island is a mysterious continent that mainlanders have hardly been to - Ghost Fang.

Whirlpool Island is located in the heart of the Lost Lands, and the average land dweller, including coastal fishermen, has a hard time coping with the spiraling fjords and strange currents, treating it as the end of the continent – the "end of the earth", and trying not to approach it.

The first people to live there were some people who had a complicated blood relationship with the Silky Demons and were always rejected by the Silky Demons - "Foggy", and they regarded it as an ideal land habitat.

Then, the various pirates who had friendly relations with the misty used it as a temporary base for storing treasure and anchoring and recuperation.

Subsequently, the merchants who had business relations with the pirates saw Vortex Island as an ideal transshipment point for their goods, and invested in the pirates to build trading docks and storage centers there.

Later, the Fog Demon also established another territory with the support of the Motuo people.

Vortex Island began to develop. A total of hundreds of large and small towns have been established there, all of which have developed from the trade port, all of which were funded and established by the Motuo people, representing nearly 100 Motuo people's chambers of commerce.

The technology of the Kiska and the metallurgy of the stingers were also introduced to different cities through the commercial operations of the Moto.

In addition, other coolies, fugitives and hermits living there have established some villages on the island.

Vortex Island has actually become a small but complete periphery world, and the Merge Merchants are the actual controllers, but basically do not go; The pirates are the builders and managers there, and the sparkling are the natives of the land.

The misty is a race with a relatively awkward status, it is between the misty demon and the sparkling demon, compared with the sparkling demon, the misty demon has men and women, and the sparkling demon only has women; Compared with the fog demon, both men and women have side fins on their legs.

The misty and misty demons can intermarry, and the offspring have leg fins all over their length. Misty males and sparkling demons can also give birth to offspring, there is no difference between giving birth to a girl and a sparkling demon, and giving birth to a male is definitely not an authentic sparkling demon, because the authentic sparkling demon is asexual - "divine fertility", and only women.

The Demon believes that the existence of the Misty Demon poses a serious threat to the purity of the Demon's "divine education" bloodline, and has always regarded the Misty Demon as an evil thing; The Fog Demon could not bestow the tattoo on the offspring of the long fin on the legs, and also regarded the Misty Sparkle as ominous.

In this way, the sparkling is born an outlier without tattoos, and their friends are only pirates and merchants.

Misty has a high status among pirates, mainly as a navigator and captain.

Misty men like sparkling demons very much, and they also like sparkling demons, and many sparkling demons experience love with them, and are stimulated to lust that can produce a sense of happiness, so they are brutally hit by the mainstream society of sparkling demons.

Driven by love, the misty is not to be outdone, and the conflict and war between the two sides continues, because the misty people are small and lonely, and they have no advantage in culture and morality, and each time it ends in failure.

In the year 1193 of the Kuiba Era, a misty hero Huaisu, with the desperate help of his pirate brothers, led his people through a bloody battle to defeat the Demons, forcing the mainstream society of the Demons to accept their "petition".

From then on, the misty and the demon can have a normal relationship, but the descendants still can't get the official tattoo. This historical event is known in history as the "Misty Petition".

In the year 1194 of the Kuiba Era, Misty built a memorial altar on the beachhead of Yuanyangjie in the east of Vortex Island, and engraved the reconciliation agreement between Misty and the Demon on the stone tablet, as a historical witness, confirming the Demon's racial identity with Misty Demon.

For the Sparkling, their association with the Sparkling Demon was completely legal from now on; As for the Demons, they took the opportunity to assert their sovereignty over the Lost Lands, and for the first time in history, the Demons possessed land territory.

The year 1331 was another year of Quibal's resurrection. The Heavenly Realm carried out a meta-point attack on Lingshan, and this generation of Kuiba did not appear.

However, the strong geological changes caused by the meta-point strike made the warp reaction and magnetic pole action of the Lost Land more intense.

In the year 1337 of the Quibal Era, the main body of Vortex Island settled into an underwater warp realm.

Since the land sink was not sudden, most of the people on Vortex Island fled there.

Since then, the northeastern part of the beast country has been a strange rocky fjord and a strange ocean, and the land opposite has become more mysterious.

The main body of the Vortex Island enters another space through the warp space, which is isolated from the earth boundary, and only the warp realm boat can reach there through the warp realm.

The only known warp realm boat on the earth boundary is the warp realm No. 1 battleship of the Tree Country Navy.
