Lupa

I suddenly had the words, words I couldn't have known.
"I am Lupa. I am the all-mother, I am your guardian, your refuge, your peace. I will stand with you against all harm. Your enemies are my enemies. I share blood and flesh with you. We are lukoi, we are pack."

(Burnt Offerings, page 43, paragraph 4)
Commentary * A term used by wolves to name their female alpha leader. The Lupa is the 'mother' of the wolf pack, responsible for the emotional stability of the pack.

* She does not have to be the dominant female in the pack, although many times she is. She is chosen by the Ulfric because he would wish a mate that he can live with.

* When the Ulfric makes his choice public to the pack, he announces it in the following manner:

"This is my lupa. Know her scent, know her skin. She has shed our blood, and shed her blood for us. She stands as protector for those weaker than herself. She will kill for us, if we ask. She is your alpha."
(KD - 107)

* There have been three lupas mentioned by name in the series:

Raina - Thronnos Rokke Clan (Deceased)
Anita - Thronnos Rokke Clan
Roxanne -  Oak Tree Clan
