First of Twelve
In Antiquity, before the twelve peoples gathered and formed the great sanctuary at Blue Cavern, before Din became Zo and the the Red Gong Games began in the muddy streets of Basin, there were only the twelve elements.
Of these, the first to bond with Humankind was water. Those who cast water are called Waterwicks. Their element is quick to learn but hard to master, for while there are more waterwicks than any other Kai in Blue Cavern, the percentage of these who reach master level is the smallest.
