Hi everyone

Although I am e new member on this forum, I have been reading many theards here and find it very interesting and enlighting regarding my understanding of the books.
First of all I want to say, that english is not my mother language and I have read the second trilogy in english, so maybe that was the reason for my missunderstanding of the things I wanted to know.
My questions are:
1. When exactly did The Consult know that they need an Anasurimbor to bring the No-God back ?
2. At the end of The Great Ordeal did Achamian found out about this and was this the reason why he talket to the Mandate Grandmaster ?
3. And did I miss the origin of Achamians dreams or will this be revealed in the next trilogy ?
4. Were the Dunyain among the Consult knew something about Ajokli or was it just coincidence, that they captured Celmomas ?
I would be really thankful if someone could help me.
I was a bit confused, that Achamians role didn't go anywhere in the last book. After The Great Ordeal I expected that his meeting with Kellhus would be I don't know bring some revelation.
Strangely I believed that Achamian would become the No-God because there was the hint that Nau-Cayuti could be Seswathas son

But still I enjoyed all the books and will read the last trilogy.
