As Jork said, Kleb was supposed to die in those powerful and unquenchable waters, but it was not to be. The violent waves carried him away to the heart of the kingdom, where only a tiny but sublimely beautiful island existed, and which held in its center a jewel, a jewel of a purity equal to the purest and most transparent water that could exist. A jewel that guessed all the power of Kleb, decided to take him as a guardian, and in its case, was waiting for its owner and master.
When Kleb finally woke up, or rather, when the infinite jewel decided to remove the spell that for him was absolutely nothing, the latter quickly made the young mage understand what it was. What had happened to him and what the jewel, the heart of the nameless kingdom, expected of him.
