Placido Salat was a beefy man with prominent cheekbones and a florid face. He was a teaching chef at the Bene Gesserit complex on Chapterhouse, and was regarded by the Mother Superior Darwi Odrade to be one of history's greatest chefs, his signature dish being beef placido (low case his choice). As a special treat for Darwi Odrade, Placido would create an oyster stew that reminded Odrade of her youth before being taken away for Bene Gesserit Training. One of Placido Salat's students was Duana, Darwi Odrade's personal chef.
