I did that. I lit up the temple and was rewarded by Ziva and the swamp girl having sex with the MC. Am I supposed to go to the temple again?
If you have:
Bought the robes for Ziva & Caleah;
Done "Ring the bell" & had Ziva / Caleah 3some;
Invited Beth (Stable girl) on a date & she has accepted;
Talked to Erevi about the summoning spell;
Built the crib for Erevi's baby.
Then she should put the baby in the crib & move on.
You won't be able to knock her up again until the child has grown & gone questing with you.
When you went to the dragon cave for the big gem, there was a patch of burnt ground outside the inn.
The Enhanced Fertility recipe is in a box there.
