Hermione Granger: Heir of Ravenclaw and Seer
Private settings:
Hermione's ancestors were reclusive purebloods who had been doing well in the Muggle world. Her father was a squib, so she had been living in the Muggle world. After receiving the notice later, he took her back to the Ravenclaw Manor, which had been closed because she had no magic power. There were many historical materials in it.
Thousands of years ago, the Slytherin family was also known as the Peverell. As time went by, the Peverell family gradually retreated, and the Potter family began to appear, and most of them chose to go to Gryffindor, and very few awakened the feathered serpent blood.
Godric Gryffindor had a younger brother, but he was lost during the siege by the Holy See. Later, Sara found him. In order to protect him, Godric changed his name to Malfoy and placed him in Slytherin. At that time, almost all the young wizards who had awakened their blood were in Slytherin.
Thousands of years ago, the four founders of Hogwarts were tied for the highest amount of money wanted by the Holy See. Except for a few of them, all people with the same name as them would use pseudonyms, and only those who were familiar with them would know their real names later. This phenomenon was very common in the wizarding world at that time, and young wizards would even give themselves several pseudonyms, even in school.
But later, with the loss of historical data, people gradually forgot their former names.
Purpose: Reversing fate
