A few questions about the story (possible spoilers)

Hi everyone!
I have trouble realizing who was the initial author of that famous riddle "What can change the nature of a man?". After completing the game I've come to the following variants:
1) The very first incarnation presented this riddle to Ravel as a payment for making him immortal.
2) The riddle was originally Ravel's, but only the first incarnation managed to answer that question.

I would be very grateful if you share your thoughts about this.

Yup it was Ravel's indeed, she asked the first incarnation and then the last one. There's a topic somehwere in these forums on the answers we gave to her, or which we feel is the right one.

So the article is wrong then? Seems I need to play through that dialogue with Ravel once again, just to make things clear.
And a question about Dak'kon's Unbroken Circle: we learn from Practical incarnation that artifact was made up by him in a week, does it mean that Dak'kon's belief is based on a forgery?

[valkir]

Aye. While evil in his intents, the Practical Incarnation was very cunning and he managed not only to enslave Dak'kon for a given period of time, but also to bound him to all the future incarnations through making up what you could almost call a religion.

Curious though that you could learn from the Circles without recalling that it was actually you that produced them...
