Shinji..... You juz find a lever to open the door. You know those lights at the walls? Try them near the door. That should open the door. But a word of warning when you are at the 7th area, you will expect some "falls".
Anyway, can someone help me with the main quest? After er.... I think after the treasure hunt and Mao. I can't seems to open one of the bridges that lead to Natia.
I found the first switch but it only open on top-right bridge...
