Back to Novigrad
Once you’ve finished Novigrad Dreaming and if you let the Golding Sarah remain in the house after a few days you’ll find a new notice on the notice board in Heirarch square. It’s a notice warning of the haunted house and a cheating merchant.
Return to the house to find Corinne Tilly and the Godling happily living together. Corinne took a liking to Sarah and bought the house so they could live together. Once you’ve gone back to visit them this quest will be complete.
