In Act 3 of Baldur's Gate 3, players can learn that Raphael is currently residing in the Sharess' Caress, a brothel on the South Span in the Rivington region. He's here to offer the party a deal: he'll give the party the Orphic Hammer, an item that can free Orpheus, and in exchange, the party must give him the Crown of Karsus once they defeat the Absolute.
