To Gaine, those puppets were crude junk. If it was not for Saleen's request, he would have rather spent 1000 years to make a level 18 figure, instead of making tens of thousands of junk ones within three months.
Saleen did not rush to craft the weapon he had in mind after familiarizing himself with lightning magic patterns. He chose instead to continue interacting with Gaine, and went about familiarizing himself with the astrological arts that Gaine passed on to him.
It was easy to advance in astrology in their earlier stages, but it got increasingly difficult as one progressed. As such, the likes of Gaine were few and far between throughout ancient times. Gaine admitted as much. There were simply too many people who wanted to know what their fate held, and most were simply able to go with the flow, becoming little more than a speck of dust in the vast rivers of fate.
