Randolph Chase

Randolph Chase is the older brother of Frederick Chase and Magnus's mother, and the uncle of Magnus Chase and Annabeth Chase. He is a former Harvard Professor.

The Sword of Summer
Due to being the eldest, Randolph gained ownership of the Chase family mansion after his parents deaths. One Thanksgiving, Randolph gets into an argument with his brother and sister, causing a rift between the family.

Ten years later, Randolph calls Frederick and his daughter Annabeth to tell them that their sister's son Magnus has been missing for two years since his mother died. He goes to the city shelter at The South End, but has no luck in finding Magnus.

Randolph returns to the mansion and finds Magnus in his office. He tells Magnus that they don't have much time and says that "they" will be coming to kill Magnus now he is sixteen.

Appearance
Randolph is described as being barrel-chested with a trim white beard with a skull cap of grey (formerly black) hair. He also carries a polished wooden cane with an iron tip.

Etymology
Randolph is an English name derived from a medieval name composed of rand (shield) and wulf (wolf). Roughly translated the name means "Shield Wolf".
