I understand what your getting at and I am aware that "Perception" breaks the cast when compared to the other surges but I also think that is why this surge remains un-named at this stage.
Information/Data maybe even Propagation would be better suited to match the other nine surges but dose not give a good one word description of a surge.
a quick look through a thesaurus give me these options:
Awareness, Recognition, Illumination, Detection,Espial, Revelation.....
Again all these words are somehow inappropriate to me in some form though the best fits would be Information or Propagation so far, but I still think perception is the best way to describe how the surge "functions".
who knows i'm most likely miles off the mark
Edit: without hijacking the thread anyone got other idea's for what the final surge could be?
