Estelle Blofis is the daughter of Paul Blofis and Sally Jackson and the younger half-sister of Percy Jackson.

The Trials of Apollo

The Hidden Oracle

Percy mentioned his unborn half-sister to Apollo. He said that he wanted to meet his sister when she is born and be there for her when she is in need. This was also the reason he could not help Lester to turn back into Apollo.


Percy Jackson, Estelle's half-brother.

Magnus Chase and the Gods of Asgard

The Ship of the Dead

While training with Magnus Chase in Boston, Percy mentions that he has to go back to New York and babysit his newborn baby sister, revealing her name.


  • Estelle is a feminine given name meaning "star" that originates from the southern region of France and surrounding countries known as Occitania.


  • Estelle is named after her maternal grandmother.
  • As Sally Jackson has Clear Sight, the ability to see through the Mist, Estelle may inherit this ability as well.
  • Given that Sally was seven months pregnant in The Hidden Oracle, which takes place in January, Estelle was probably born in or around March.
