Is there any content after the prologue? It just says I should go out for what to do next.
On the right hand side of the 1st floor, a couple of portals open up at this point. the righthand one leads to a house with a bunch of npcs. They do a bunch of stuff like enable/disable viruses like lewd crest and big boobs, but one seems to advance/set the story to certain points, which you can use to progress to certain points. The first option lets you pick fights with a couple of guys outside and in the shopping mall for example.
I'm a bit stuck with the second however. I can visit spira in the jail, and go to my room to communicate with her and sleep, after which a get a message from Diad, telling me to meet him at the rest point in the cave of silence. I then get a new objective saying to meet him in the exploration area. No idea how to get to this area however, is it actually available or is this the end of this story thread? I can't leave the main building to enter the town area at this point, as it says to go and meet diad, but I can't find him anywhere.
Edit: I'm an idiot, and solved my own issue 10 seconds after posting this. Talking to the receptionist on the 1st floor central area gives options for dungeons to visit. guessing one of these is where I should go.
