Delphini mottog profetian från Rodolphus Lestrange.
DELPHI: I am from the future. The child of Bellatrix Lestrange and you. I was born in Malfoy Manor before the Battle of Hogwarts. A battle you are going to lose. I have come to save you.
[HARRY/VOLDEMORT turns. She meets his eyes.]
It was Rodolphus Lestrange, Bellatrix’s loyal husband, who on return from Azkaban told me who I was and revealed the prophecy he thought I was destined to fulfill. I am your daughter, sir.
Det är inte riktigt klart var han fick profetian, men det har nämnts på Pottermore att vissa föräldrar besöker " namngivare " som tillhandahåller allmänna förutsägelser om ett barns framtid.
A certain sector of magical society, however, follows the ancient wizarding practice of consulting a Naming Seer, who (usually for a hefty payment of gold) will predict the child's future and suggest an appropriate moniker
This practice is becoming increasingly rare. Many parents prefer to 'let him/her find his/her own way', and dislike (with good reason) receiving premature hints of aptitude, limitations or, at worst, catastrophe. Mothers and fathers have often fretted themselves silly on the way home from the Naming Seer, wishing that they had not heard the Seer's predictions about their child's personality or future.
