So I've managed to beat the game - siding with the Huana because skyrim is for the nords - all the while awaiting a response from them that they have recalibrated their machines. I'm about to start a new game, but I'm quite curious what exactly passes time for this quest. I've progressed several other quests, such as companion quests, but this one simply refused to progress to the second point. I even did the other quests they had available in hopes that those quests advanced this one but it seems not.

 

I was hoping to do a Vailian themed playthrough and side with either them, or the Principi, but if I can figure this out I'd rather side with them.

That should happen after your return from Ashen Maw.

Hi Slvrbuu,

 

 

It should continue from that point once you finish all the VTC quests leading up to it, and you will talk to Castol. Note as mentioned above, you will need to have completed Ashen Maw in order for this to trigger.
