Seth's goal was to craft Silk Threads Sew Art depicting all the dragons he had faced. But it won't be one use art, rather one that can be animated repeatedly.
However, he knows it will be hard to achieve, so he will just make a continuous animation before he plans his way forward.
Another thing he wanted to achieve with this was to change the presence of the dragon to his own. That was to say, every time a dragon animation happened, the dragon will have the original dragon abilities, its aura but presence was different.
Without Red Signature Book Halo to shield him, they might know and even try to do something to him. So, he wanted to transform the aura and presence to his own, or to something that can't lead them to him.
This plan has been in his mind since when Retina told him that Dragon Pulse will attract trouble to him. Now he doesn't even use it alot.
