This seems to be a bug.
I have the same problem, after finishing the Grove Ritual I am supposed to meet Adrasteia/Saradomin in the Falador Throne Room.
However, only Adrasteia is there and only offers me a review of her prvious speech/song.
World hopping and logging in and out and in and out and in does not help.
Quest journal states "Now that we've completed the mock-rituals for the Edicts, I should inform Saradomin of what we've learned".
So, apparently I am caught in a cul-de-sac.
Any ideas what to do - despite leaving RS, blowing up my machine and going outside?
