Baldini is the ghost of man found at the Temple of Nimir under Lanilor Lane in Aleroth during the events of Divinity II: Flames of Vengeance. The uncle of the alchemist / illusionist Chanelle, Baldini was a perfumer to kings and queens before his untimely demise. His nose led him to the temple in search of the rarest scent in Rivellon, where he ascended the platforms and fell to his death after being overwhelmed by the smell of the flower he found there.
Baldini's Bouquet – Baldini's ghost asks you to retrieve The Flower that doesn't Exist from high above you in the Temple of Nimir, and bring it to his niece at her shop, Chez Chanelle. She can brew it into a unique perfume, which can be brought back to him. Smelling the resulting perfume, which he gave his life in the pursuit of, will allow him to pass to the Hall of Echoes in peace.
Baldini can be mindread for 15000 exp, revealing: "When I was all the way up there where the flower grows, I noticed a button hidden at the back of a chest. I wonder what it does?" Note that this is not necessary, the button can be pressed without it.
