So you might remember that awhile ago I created a thread questioning the validity of Vahlok the Jailors story and whether he actually defeated Miraak. You'll find it in this thread.

I took the liberty of mailing Gstaff to ask him about this and I did get an answer, but due to my busy life I haven't had the opportunity to post it until now.
I hope this clears things up for everyone.
