"Her name was, Aziza, Salazar had found her egg in Algeria, giving her a name of Arabic origin meaning strength power might and precious. He had placed her there to protect the students from Muggle threats. Salazar never wanted to wipe out Muggleborns. He had taken some under his wand as proteges, unfortunately, his favourite, the most promising, a young girl Ainsley who was a gifted Legilimens and Occlumens at thirteen. Unfortunately, she had been caught in the witch hunts and burnt to death at fourteen. That was when he bought Aziza into the school and hid her in the Chamber. He then tried to have Muggleborns taken from their families and adopted into the Purebloods to save them. What legend does not tell you is that Godric, who was his best friend until the end, supported him. He did not want to take children from their parents and instead wanted to monitor them and any sign of abuse have them taken then. They fought over it yet but not enough to break the harmony between the four friends. Rowena completely agreed with Salazar and Helga with Godric, but they comprised, they would do as Godric and Helga wanted but if too many were being taken from abusive Muggles that they would change to Salazar and Rowena's plan. All four founders knew of Aziza. All four had helped build the Chamber to keep her comfortable."
