- A wolf pup - Lupo (silver with a white underside) - Found after she joined the Organization, starving and nearly frozen to death. Anelixi cared for him and has kept him ever since.
- A peregrine falcon - Dusty (typical peregrine falcon appearance, but has a twisted wing) - Located out in some woods with a broken wing. Anelixi couldn't put her wing back in place, which means she can't fly, but Dusty is well cared for.
