Natalie Chase

Magnus Chase's mother was the sister of Frederick and Randolph Chase, the mother of Magnus Chase and the aunt of Annabeth Chase.

History
When Magnus was six, his mother and her brothers got into a huge argument at Thanksgiving, thus causing a rift in the family. Magnus never knew what the argument was about though it possibly had something to do with Randolph demanding something from her and she refusing to give it to him. Eight years later, when Magnus was fourteen, his mother was killed by something with "glowing blue eyes".
