Yet Andar still observed for a while without noticing any visible change in the demeanor of this creature that came to relax in his Spirit Matrix, and there seemed to be no adverse reaction with his Engraving Tiles so he left it for now, after the tests, he would begin his investigations.
As part of his Meditation Art, he should have access to the understanding of how this creature came to reside inside him and what abilities it had, but for now, he had other priorities. The prize that was to be given to him by the Archmage would surely be important and would be of invaluable help to him at this level of power.
The same thing goes for his Endless Vault which was merged to his spine and existed in a kind of spectral state. He could not investigate it now, but Andar quickly discovered a use of this treasure, which was to store items and even people, like himself.
