This is my second playthrough and am at the point where I go into the excavation and talk to the Water mages. I did that, bu they won't give me the quests to gather ornament pieces. I ran out there with Lares and he gave me his piece to give to Saturas. I did that and a couple of little quests in there, but now my dialog options with Saturas are "Will you teach me something about magic?" and "End." I thought he would give me a map and tell me to gather ornament pieces to open the portal--that's what I remember from my first playthrough. I went and spoke to Orlan, Vatras, Lares, and Cavalorn because they are in the Ring of Water and might have some unresolved part in it, but they offered no help and there was nothing unusual I could say to them. Oh, and my current quests list does not have "The Portal," which the walkthrough on World Of Gothic says is the quest name, so I know I don't already have it.
Please help. Thank you

Edit: Never mind. It was something simple. I just needed to talk to Nefarius and had not seen him yet.
