Claudia is a Roman Legacy, a descendant of Mercury. Her notes on her first few days at Camp Jupiter helped create Camp Jupiter Classified: A Probatio’s Journal.


Early Life

Claudia was born to an unnamed father, who is a grandson of Mercury, and a woman named Cardi who is not around anymore.

Learning her Family’s Lineage

On her twelfth birthday, her father revealed that they are descendants of the Roman god Mercury, with him being the messenger god’s grandson and her being his great-granddaughter.

Start of a New Life

Soon wolves came for her and brought her to the Wolf House. Their she survived Lupa’s training by building traps and evading the wolves as much as possible. After completing Lupa’s training she headed south to the San Francisco Bay Area.

Mercury, her ancestor

During her first few days at Camp Jupiter she was placed in the Fourth Cohort with little trouble, she later learned it was due to a need to refill their numbers after the Second Demigod Civil War.

The following day she finds a letter she thinks is from Mercury and takes it, does poorly during weapons training, and bumps into Frank Zhang leaving his father’s temple and laughing at the son of Mars.

The following day she is asssigned to clean the trash out of the aquaducts along with a fellow Probatio named Blaise, a son of Vulcan, who leaves her when he fills his sack. Claudia gets lost and eventually finds a way out, coming face to face with Reyna Ramírez-Arellano and her mechanical dogs as a result.


Claudia is said to take after her mother, with dark wavy hair, dark eyes, high cheekbones, and a large nose.


Claudia is shown to be resourceful, building traps for Lupa‘s wolves when at the wolf house.


  • Engineering Skills: Claudia is shown to be a skilled engineer despite her young age, being able to construct traps during her training at the Wolf House.


  • Claudia is an Italian feminine given name derived from from the Roman name Claudius, which in turn means “lame, crippled”.


  • Claudia is the second legacy to have a point of view in any of Rick Riordan’s books. The first being Frank Zhang.
    • However Frank is also a demigod, a son of Mars, in addition to being a legacy of Poseidon. If Claudia is only a legacy of Mercury, then she is the first point of view character to be just a legacy.
