Lupa

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 presumable has a similar pack with the gods as Chiron that is to say as long as she is needed to train half-bloods she 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.
