I wonder if the Q in IQLUSION is notable, in K3 it mentions:

    FROM THE MIST X CAN YOU SEE ANYTHING Q ?

and in K2:

    X THIRTY EIGHT DEGREES FIFTY SEVEN MINUTES SIX POINT FIVE SECONDS NORTH SEVENTY SEVEN DEGREES EIGHT MINUTES FORTY FOUR SECONDS WEST X LAYER TWO

Maybe the location in K2 is related to the position of the Q in K1 somehow.
