While Narak was planning the annihilation of all other civilizations on his creator's planet, Alvine was in the dimension with Dalvine while his clone accompanied Sylvia on the planet of Kelspies without her realizing that the person who accompanied her was the copy and not the original. To be more explicit, it was Alvine's body that was with Sylvia but as a result, the soul that possessed his body was his artificial soul and not his real soul.
Stubborn as he was, he had not abandoned his idea of testing the exchange of the body with his artificial body. But to his astonishment, the test was beyond his expectations. The fact of moving from one body to another was so natural for him that he felt like he was born with this skill. It was also an opportunity for him to test one of Dalvine's theories.
