The Heap family is an ancient Wizard tribe whose current generations live in The Castle. They are notable of being the main characters in the Septimus Heap series, and their seventh son, Septimus Heap, is the protagonist of each book sometimes along with his adopted sister, Jenna Heap (the Princess ).
The father of the family is Silas Heap, whose wife and mother of his children is Sarah Heap. Their seven sons are Simon, Sam, twins Edd and Erik, Jo-jo, Nicko and Septimus. The family also adopted Jenna Heap.
During the events between Magyk and ending of Physik, the family seemingly breaks apart, since Sam, Edd, Erik and Jo-Jo moves to forest, Nicko was trapped in the past and Simon betrayed everyone by accepting an Apprenticeship to DomDaniel. However, in Syren, Nicko is reunited with his family and in Darke, Simon is ReNewed. The younger boys, Edd, Erik, and Jo-Jo grew somewhat lazy in the forest but Sam remained aware and even helped Septimus and Jenna in Queste. In Fyre, the family is completely united for part of the book. Sam is the only one to return to the Forest after the events of the final book.
After the events of Fyre, Simon accepts an Apprenticeship to Marcellus Pye, Sam returns to the Forest with Wolf Boy, Edd and Erik accept apprenticeships at the Wizard Tower, Jo-Jo gets a job at Gothyk Grotto, Nicko finishes his apprenticeship with Jannit Maarten, Septimus continues and completes his apprenticeship with Marcia and Jenna is crowned Queen.
