Riordan Wiki

Shen Lun was the great-grandfather of Roman demigod Frank Zhang. He was also a legacy of Poseidon.


Shen Lun went to Camp Jupiter in the early 1900s because his family had roots connecting them to the Roman Empire.

Despite being a legacy of Poseidon and a descendent of Periclymenus (a grandchild of Poseidon), the Roman Legion accepted him into the camp because of his powerful ability. Just like Periclymenus, Shen Lun had the ability to shapeshift into different animals, a gift passed down through his family. Although he was a legacy of Poseidon, because of his Roman blood everyone believed he was a legacy of Neptune.

Life in the Legion and Banishment from Camp Jupiter

After Shen was allowed into Camp Jupiter, he was disliked and looked down upon due to being Asian, his relation to Poseidon (Neptune), and his unusual ability, even though he had Roman ancestry in his lineage.

After the earthquake of 1906 in San Francisco, Shen Lun was accused of causing it, being that he was a legacy of the god of earthquakes, Poseidon. Despite Shen not having that kind of ability and with no evidence that he had caused it, he was banished from Camp Jupiter and New Rome. Years later, his name was still resented by members of the Legion. It's suggested that he was blamed out of racism due to his Chinese heritage.

After his banishment, Shen Lun relocated to Vancouver in southwestern Canada and had at least one child, a daughter.

Poseidon, his ancestor

Before Frank leaves for Camp Jupiter, Grandma Zhang hands him a note with an apology for what Shen Lun had done, and tells Frank to give it to the Praetor of the camp. Reyna is the one who Frank apologizes to, but she orders him to not mention this to anyone. Reyna later tells Percy Jackson that if anyone found out about Frank's family history at the camp, it could cause him trouble. Percy is confused, but Reyna brushes off his questions.

When Frank, Hazel and Percy visit Grandma Zhang during their quest, they learn of Shen Lun's innocence and that Grandma Zhang had wanted to Frank to apologize on his behalf as more of a preventive measure. Grandma Zhang suggests that Shen Lun was framed for the earthquake out of racism and tells her grandson that that power isn't even their family's gift anyways.

After Frank's role in saving New Rome from Polybotes' army and returning the eagle standard of the Legion, there is talk about restoring Shen Lun to the Legion's roll of honor as people finally acknowledge his innocence in causing the 1906 earthquake.


  • Shapeshifting: After Poseidon blessed Periclymenus with the ability to transform into animals, Periclymenus passed this gift on to his descendants. Shen Lun was able to use this ability, being able to transform into any living or mythical animal. The true extent of his abilities is unknown.


  • He is the first known Greek to join the twelfth legion.
    • However, he could have claimed to be descended of Neptune, rather than Poseidon because he might have thought he was Roman rather than Greek.
  • He is the first known demigod or legacy to be exiled from a camp.
