Aniu is the product of a one night stand, her parents were strangers and after sleeping together they separated easily. Aniu's mother, Aleu, didn't have a maternal bone in her body. Aniu was the only pup to survive her mother's first litter, and after Aniu was weaned Aleu dissapeared never to return.

Aniu was raised by her grandmother, Saba, an elder of eight years. Saba named Aniu, the Inuit word for snow. She raised Aniu to follow their ways and taught her how to survive. Aniu was devastated by her Nan's death and wandered aimlessly as a yearling.

Though Aniu had no destination in mind, she soon came across a group of wolves that she joined easily. Aniu came to find that the leader was a tyrant whom expected things to be traded for his 'protection.' Aniu never gave him anything, due to the fact that she slept in her own den and hunted for the pack. Amongst the pack members she met Layla, a young girl not yet a year old. Layla lived with abusive parents and was being traded for protection.

Once Aniu found this out she snapped in one of her famous moods. She confronted the parents, attacking the mother and being dragged away by Layla's father. Once it became clear that they were not to come near Layla again, Aniu went in search of the child and found her being attacked by the leader, Sumac. Aniu faced off with him, being blinded and having half her ear torn off in the process. Aniu killed Sumac and fled with Layla at her side.

Overtime Aniu became a mother figure to the young girl, passing on the same knowledge Saba had taught her. It was only just after Layla's first birthday that the young wolf wandered away in the early morning and was attacked by a lynx. Aniu fought with the lynx, whom damaged her ear and would later cause her to go deaf. The lynx fled, having decided Layla wasn't worth the effort. Layla succumbed to her wounds, bleeding out only minutes after.

Aniu was heartbroken, having lost her adopted daughter, and once more wandered. She has found herself in Teekon Wilds after wandering, beginning to get over Layla's death.
