Despite having a name implying she'd be best suited for the role of Pupsitter, Pelt of the Newborn Fawn is a strong and capable hunter. She did spend quite a while as a Wanderer, after all. She knows how to look out for herself.
Knowing that her name casts her in something of an unwelcome light, she prefers to go by "Pell" as opposed to the more traditional "Fawn." Some packs would raise eyebrows at this -- names are sacred and always chosen by the mother -- but Ambercloud does not see reason to raise issues where there are none. It's the wolf that matters, not the name.
