Loimu was born in the same litter as Asteria. But was raised by Circinus and Vela from puppy to adolescent. Her personality and attitude drove her birth mother Artemis mad. All of her children should have been prim and propper but Loimu stuck out like a sore paw with her pessimistic and sarcastic nature.
The pupsitters tried to help Loimu but there was only so much they could do when Artemis was higher up in the hierarchy than Arctos.
Asteria was ready to go against Proximas order on chasing members out without her permit. Loimu ran to Circinus and Vela crying about her mother wanting her dead. Circinus was so full of rage and hate towards her scouting sister and told on her plans.
Artemis was demoted and Loimu got to stay with Auntie Cir and Pawpaw Vela. That time was sadly cut short when Vela died of old age and two days later Cir slept away, neither of them got to see Loimu growing in to adulthood. Perseus promised to keep his younger siblings Loimu and Saraste safe.
