After CS, speak with the guy again, he's by AH on top level. Get key item, and then go to a new Cavernous Maw to enter Abyssea. I went to Kons Highlands and the maw was right by zone into N. Gustaberg.
From there, I don't know what to do... I entered solo so it's pretty boring for me :/
Update: I was able to complete a quest (no reward) by speaking with Ayame, who referred me to another NPC, and then running around the camp and checking Repair trunks for key items (one was hidden behind Maw). Again, not sure what it does, but it's something.
