Breath of Fire help needed

I’m replaying the first BoF game, and I’m at the part where you go through the cave to get to the Dark Dragons’ ship. I’ve beat the Squid boss, but now I’m stuck. I know this happened to me last time I played the game, but I can’t find the next boss. Help, anyone?

Loot the place and get back to Auria, just check the docks and talk to the Captain so you can use the Dark Dragon ship to continue.
