Just what the heck is it? I can think of how it got there. Maybe it was also through a rift in space, just like what happened to Little Four & the learning space, they got into Ling Lan. We still don’t know if it was by chance or by design.
It needs to be something that would make a local go "Hey! This is good stuff. I should embed it in my flesh so that I am never apart from it and it is harder for others to detect."
Is far as i know, the learning space and talent snatcher/copier systems have no physical form....
It seems like the Mandora universe is becoming more and more important in the plot now. Can't wait until the mysteries are solved. Waiting for Little Four's awakening and for Boss Lan to find a way to create real bodies for the instructors.
