Augusta Tower (200AF) - Find Paradox Agent Type C
This is definitely the hardest Paradox Agent to find. After obtaining the mission from the console, head back down to floor 49. Look for an area where a yellow ring ends, then stand across from that and look down to see a floating item box very far down. Toss Mog against the pillar to get him to land safely near Paradox Agent Type C. Bring it back to the console to get Fragment of Time - Difference Engine, as well as Access Key 13.
