It reminds me a bit of Caspar Houser's life. If I actually remembered the word for “wolf”, it could have been a great reference to the foundation myth of the city of Rome.
EDIT: Just saw that it is wilk, which sounds close to the Czech “vlk”. So, I guess that it could translate to “Wśród wilek”?
I find this website very useful when trying to work out the case. http://odmiana.net/odmiana-przez-przypadki-rzeczownika-zwierzę
