what the heck are the symbols?
sure, i get that they form a cube, but why or how do they control the elemental powers of the toa?
as kopaka said in comic #1
"interesting. the power is within me. the sword is but the focus".
so why, if the kohrak-kal took the symbol, would kopaka lose his power?
And why is there and exo toa next to the nuva cube in the centerfold of comic #9?
