15 out of 20. Though the oblivion question being in there doesn't make sense. Also the question about who holds keening should be nobody, because it's sitting in the pedestal in the dwemer citadel. (still got it right, but seeing as how detailed they went on some questions, it's interesting that they didn't with this question).
I also don't think that the house dagoth call corprus the divine disease, but it's called the divine disease by everyone else (I distinctly even remember doing a mission for the temple where it's referred to as the divine disease), it doesn't make sense that the dagoth followers would call it a 'disease' when they don't see it as one. I thought they called it Dagoth ur's blessing or our master's blessing.
