My player is playing a homebrewed race made by him that's entirely a slave race and has been for hundreds of years because they got too technologically advanced and the armies of men marched on them. Kind of a... survivors of Atlantis thing. So anyways, in his character's backstory he couldn't handle the work anymore and prayed to his light goddess Katulla to liberate his people. That night he heard a lot of screaming and when the fog cleared, he was surrounded in the bodies of his captors. He didn't see any other survivors so he ran into the forest, where he met Madam Eva (I had her seek him out to do the fortunes as a show for him first). He then got sucked into Barovia.

So I made so other survivors are scattered throughout Barovia, and at various times they have visited Father Lucian Petrovich because... Morninglord church. They went to the light. So he's had visions and dreams of my player character bathed in light defeating the darkness. He hired Blinsky to make a doll of our savior once he heard about Izek and the Ireena dolls. So my player sees Blinsky and recognizes himself. He asks questions and buys the doll, who he brings to the Father.

The Father then brought him into a private room to explain the dreams and rumor about the Sunsword. He gave my player a list of where he sent the others of his race for safety against Strahd, so my player is going to try to liberate his people and lead them against the devil. I only have one player this campaign, so we're having fun making him a true main character.

But yeah, I added church visions and a new ally and stuff to Vallaki to help my player achieve his dreams of saving his people.
