Question about TWW story (SPOILERS)

Hi all,
I've really been enjoying TWW story so far, but I'm a little confused. I was following the campaign, and it took me to the Azj-Kahet where I was involved in a political plot to overthrow the corrupt queen. Things escalated to this cool moment between Alleria and Xal'Atath, and then it just ended and now I'm wondering around and all quests are giving me something called Kej.

I have no idea what's going on. Did I skip a zone, or miss something? I'm not level 80 yet either, and I didn't do any side quests as I was wrapped up in the MSQ - but is that it, is it finished? I'm not sure what happened.
