I went to Aerama's place, inside the portal, past the cheeses, swam, disabled barrier, dispelled illusion, got the loot, and thought I was done with it. But now, a few hours later, I have two more objectives on that quest (I think they appeared after I completed the Nobleman's Statuette quest that I forgot I had) that tell me to Search Aerama's Residence using Witcher Senses and to Use Aerama's artifacts to activate the portal, but I don't know what i'm supposed to do, witcher senses don't reveal anything
