Lupa

History
Lupa is the she-wolf that reared Romulus & Remus she is the head of the Roman camp much as Chiron is at Camp Half-Blood. She presumably has an identical pact with the gods as Chiron dose which means that as long as they are needed to train half-bloods they will remain immortal. She can speak both Latin and English. She is the head of a pack of good Wolves unlike those lead by Lycaon.
