Italy

It is unknown exactly what year the Kingdom of the Wicked series takes place in, though it is known to be sometime in the 1800s. The majority of the first novel takes place in Palermo, Italy, where the twins Emilia and Vittoria were born and raised.

Sea & Vine
Sea & Vine is the name of the restaurant owned by the di Carlo family in Palermo. Everyone, including Nonna Maria and the twins, helps in the kitchen and service. The first book, Kingdom of the Wicked, begins with Emilia in the restaurants kitchen with her mother and Nonna, with Vittoria notably absent.

They mostly serve classic Italian dishes and delicacies. It is unknown exactly how popular it is amongst the locals, but Emilia notes that it gets busy around the dinner rush.

The Monastery
The Monastery is where the brotherhood originates. Emilia volunteers goes there once a week to cook them dinner, including Antonio, one of the newer members. It is here that Emilia first discovers her sister Vittoria's body, and when she first lays eyes on Wrath, who was standing over her at the time.

The Monastery serves as a fairly central location throughout the first book, Kingdom of the Wicked. Later in the novel, Emilia finds Claudia here after she has fallen ill to her use of dark magic, her mind stuck between two worlds. Sometime after this, Emilia learns, in the Monastery, that Antonio was the culprit for the witch murders around Italy, and that he was being tricked by someone else into completing the tasks.

The Cave
When Emilia first summons Wrath, it is in a cave by the Coast outside of the city. She describes it as cold and dark. Wrath then spends three days trapped here, with Emilia coming and going, bound by the spell she cast. He is released just in time to leave and save her from the Viperidae.

The next time the pair of them visity the cave, it is at the end of the first book, when Emilia goes to Wrath to complete the deal between her and Pride. Wrath has her sign a contract before he magically teleports them away from the cave and into the Seven Circles, also known as Hell.

Di Carlo Family Home
The Di Carlo family home is somewhere in Palermo Italy, within walking distance from the Sea & Vine restaurant and the Monastery. All of Emilia and Vittoria's family lives there, including their parents and Nonna Maria. On the second floor, Emilia and Vittoria share a bedroom, and have since they were first born.

Later in the first book, Emilia has the house warded by Claudia so as to help keep the Princes of Hell away from her family. It doesn't work, however, as after Claudia falls ill and Emilia sends her to the house with Antonio, Envy intercepts them and forces her to undo the wards, giving him access to the home and those inside. Envy's plan is then foiled when Nonna Maria fights back, banishing him from their home with an enormous amount of power.
