Jyorta wished to imbue the concept of Aura Induction as the core fundamental law governing his hallucinated world. That way, every presence within it would be considered as a tattoo. There were still some complexities regarding this issue, but he wasn't without solutions. All he needed was time to make the deductions. After all, he already possessed the necessary information.
When every presence in his world was treated as a tattoo, he could activate his plans; that was, for every tattoo to make use of the core fundamental law of their world, Aura Induction. When a tattoo kills and devours another tattoo, it would activate Aura Induction, inducing the presence of the slain party into itself.
It would be a process similar to digestion as its form tries to digest and incorporate the foreign presence into its own. This way, either the tattoo would also gain the ability of the tattoo it had devoured or create a new ability by fusing the respective two's abilities.
