Rowena Ravenclaw, one of Hogwarts' four founders, had a daughter named Helena Ravenclaw.
Perhaps Helena took her mother's surname because Rowena's brilliance was simply too dazzling. What was certain was that, as her daughter, Helena had always made surpassing her mother her goal.
Helena spent her entire life trying to escape her mother's shadow. She hoped that her wisdom and accomplishments could exceed Rowena's, but she made the mistake that most people made.
Helena mistakenly believed that all of her mother Rowena's wisdom came from the Diadem upon her head.
She perfectly inherited her mother's pride, but unfortunately lacked the confidence needed to support that pride.
Rowena Ravenclaw's influence was simply too great—so great that Helena lost faith in herself. She became somewhat obsessed, stealing her mother's Diadem and fleeing.
Proud Rowena told no one about her daughter's escape. She acted as though nothing had happened.
But she was suffering inside. In private, she asked a noble knight who had long been devoted to Helena to bring her back.
This knight was also a talented young man with considerable strength. At the same time, he had repeatedly professed his love to Rowena's daughter, Helena.
The knight eventually found Helena. By then, Helena had hidden the Diadem inside a hollow tree in Albania.
Thinking her mother had sent him to reclaim the Diadem, she hid it out of jealousy and panic, then refused his request for her to return with him.
She also rejected the knight's renewed declaration of love.
Helena was too proud. In that era, she was as exceptional as her mother.
As a woman in an age when women generally held low status, she did not indulge in romance. Instead, she was devoted to her own ambitions.
As expected, she dismissed the young knight's confession with utter disdain.
