A stuffed raven, Crenshaw is the last “surviving” bird in Bran’s avian taxidermy collection – the one Born Katherine Aelwen Lin. For the record, she rarely allows “Kate.” More accidentally blew up by introducing Suvi’s unpredictable baby-dragon magic.
Crenshaw did not explode because he’s not simply a stuffed bird, but much, much more.
He looks like a Chatham Raven, a New Zealand variety that has unfortunately been extinct since the 16th century AD.
Crenshaw probably has some stories to tell if he could talk. His official titles are Prince of Umbra, Lord of Crows, Echelon of Darkness, and Heir to the Darkseed, and he... More would literally fight to the death to keep him whole, and partially didn’t mind the explosion of his property because of the relief that Crenshaw was okay.
