Some of the other wolves in her pack describe Rook as an oddball, and she tends to embrace that label - she is rowdy, tomboyish, and cares little for etiquette and manners that other wolves espouse. However, she has a passion for training and mentoring young wolves - so much so that many of the pups in the Sisters have taken to calling her Mama Rook. She's one of the more adventurous and "fun" sitters to most of the pups - she doesn't hesitate to take them out on daring journeys to see something new, even if it might be risky.
To other adults, she's not the most popular, and might be considered antisocial. However, she's also a bit of a romantic, and is waiting to find that special she-wolf to pair bond with. Despite her interesting in raising pups, she doesn't want to have any kids of her own - due to a phobia of giving birth.
As of Year 2's Summer, she bears scars on her side from a duel with Jadwi regarding the influence she has over the pack's youth - by luck or the grace of Selene, she was able to hold her own against the attacks of the War Chieftess... and deliver her own blows which nearly killed the old warwolf. She lives in more fear than before - but takes heart in knowing that Kubla supports her in this particular conflict.
