After Narra Town?

After beating the Infernal Cult I arrived in Narra Town, and met that guy who appears from the cave entrance. I saved right after and i don’t remember where he said to go?

Where you fought mew I believe? Cave south of amphirite

Am I supposed to do anything before I head to the cave? I’m right where I fought Mew and there’s nothing here

You should go to Telnor Cave (Darkai Cultist Base)!

Yeah I think he’s right ^ sorry my memory is bad

Its just to the right of the mew cave.
