Lost!

[Cid Vicious]

I'm playing FF1, Origins Version and I'm stuck.
I've just beaten the Vampire In Terra and recieved a Ruby, which I gave to Titan.
I went to the Sage place and he gave me the Earth Rod, but he didn't tell me where I go next.
I went back to Melmond but they didn't tell me anything, I then went back to Terra but nothing's happening.
Where do I go?

In the cave where you fought the vampire go up to the stone and use the earth rod on it.

What Stone?

[Meat Puppet]

It should be in your way if you kept going in Terra cavern.
