western corner of the room, and take the stairs to level three.

from here, press the switch on the statue again. Go down, and you supposed

to see a scientist there. In any case, go past him and drop down

though the largest column. You'll find yourself in another section

of the first floor. Beat the trainer, and continue walking along

the room until you see a stairs down. Take the stairs, and you'll
