Throughout history, the All Phenomena Ocean has occasionally seen desolate islands come to life and spirit islands fall into silence. However, those spirit islands that revive for unknown reasons at most only have precedents of upgrading to high-class Spirit Islands, and those are few and far between. There has never been an instance of a desolate island reviving and becoming a top-class Spirit Island.
Unparalleled Island transforming into a top-class Spirit Island is an unprecedented event.
Across the entire All Phenomena Ocean, top-class Spirit Islands are countable, and when the news spread, which force wouldn't be tempted?
To know a top-class Spirit Island is akin to a top-class domain in existence, both capable of breeding Spirit Jade Veins. The only difference is in their scale. A top-class domain might have more than one Spirit Jade Vein, but a top-class Spirit Island only has one. Despite this, it still tempts many.
