Favonius

"Jason Grace, the West Wind has been called many things . . . warm, gentle, life-giving, and devilishly handsome. But I have never been called startling. I leave that crass behavior to my gusty brethren in the north."

- Favonius, upon meeting Jason Grace and Nico di Angelo

Favonius is the Roman counterpart of the wind god, Zephyrus. In Roman mythology, Favonius held dominion over plants and flowers.

The House of Hades
While trying to find the scepter of Diocletian in Dalmatia, Jason Grace and Nico di Angelo came across the winged god Favonius. He explained that the scepter was no longer there, taken by his master. Jason asked if he meant Aeolus, but Nico realized that he Cupid. Favonius congratulated Nico on figuring that out, commenting that he always knew the son of Hades would return to look upon Cupid's face. Jason questioned Nico on the meaning of that statement, a question the boy avoids. After Favonius remarks that the "one Nico cared for most" plunged into Tartarus, Jason assumed that referred to a crush Nico was rumored to have on Annabeth Chase.

Favonius took Jason and Nico before Cupid, recounting the story about how he killed Hyacinthus and was forced into the service of the god of love along the way. Upon Cupid's arrival, Favonius gave Nico a warning about dealing with Cupid before leaving the demigods in the presence of Love.
