Actually, looking at a list of quests again, I don't know where I am. I've done a few quests to unlock hard mode primals and one time, when I checked when the next quest opened up, it said a prerequisite was the quest 'Another turn in the Coil'.

Now I don't see that quest, so...

These are apparently what I've been doing. So, yeah. I've barely gotten anywhere in the endgame questline. Ok, me. So screw Twin for now.
