there is 3 or 4 shortcuts from macro sea to access glacier.The shortcuts are those tubes
that look like elevators. One of those elevator tubes lead to the end of access glacier.
At the end of the area you will see glare, ophanimon, sayo and the rest of the team. you
will see that they have been controlled except you and sayo. Then ophanimon will battle
you and you have to beat him to put everyone back to normal including himself. He is a
little bit hard but just use 1 or 2 revivers to beat him. I hope this will help.
