I've nearly got to the end of the game and am stuck on two quests - 'The Endless Chant' and 'Spirits of the Ancestral Moon'.

Regarding 'The Endless Quest' I've spoken to the Hermit who wants someone to replace him so I've found Krek in the Conclave who has an exclamation mark over his head but actually doesn't say anything about the quest so I've tried going back to the Hermit but all he does is chant! What am I missing?

Also, where is the Barrow of the Moon located? I've got the four totems and now can't find the altar.

Thanks in advance.
