Nightfall was not always the nomad she is now. Originally, she was born into Senkah's Pack to Night and Balto, and aspired since puphood to join the Winter Eclipse hunting group, like her father. Until she'd grown, and thus began travelling further out of the packs confines, being offered a taste of the great wide world, Nightfall adored her home.
It was when a strange wolfess crossed paths with her on one of her jaunts, speaking of a life filled with adventure, unpredictability, awe and wonder, that everything changed.
Despite Andromeda's aloof nature, the pair conversed easily, the white dame's cold remarks rebutted by Nightfall's quick wit. Over time, insults turned to bantery jokes, jokes to affection - though mild; ever dancing around the possibility of love - and affection to pleas, from Andromeda, that Nightfall leave her pack to follow her instead.
It was then that Nightfall began to doubt her contentment in the pack. The seeds of doubt sown, it was not long before Nightfall, with a heavy heart, announced her leave to join Andromeda in pursuit of a life of adventure.
Her favoured location to scout would be the glacier and prairie, adoring the absolute freedom and peace of both vast, quiet locations.
Her time with the impulsive Andromeda has altered her temperament; the once meek, quiet dame has since become combative, when faced with other wolves. Though her preference for quiet time alone, or with close wolves only, has stayed the same, her reaction to said time being interrupted or withheld has certainly changed. (More "FUCK OFFFFF" instead of just going silent n withdrawn)
Note: when she has pups, name them FallenLeaves and Nightmare to heed Grandpa Balto's tradition
