You are supposed to head to The Grotto near Quina's forest, I think North.

Does it ring any bells ? xD

funny because you ring bells to open the doors * gets shot *


You then battle the water-themed boss there and the game should take over to Dagger and Steiner, make sure you have Zidane's Trance pretty close so the water- boss is easier.

EDIT- Oh sorry I thought that this was a thread to help you out

I always get stuck, mostly with Zelda games, always the Legend of Zelda.
