I can write up any sfw short stories or backgrounds for your lions. I have no examples of bio writing but I will leave a snippit of a novel i am working on below to show what I am capable of.
Not sure what going rate is so just make an offer.

Sample:
"Screams of pain and agony echoed through the smoke filled skies. Every direction one looked was filled with fighting and bloodshed. A pained whimper choked out of a small child's throat as her father was slaughtered before her eyes. In the opposite direction an entire family was being barricaded in their home as the roof was set aflame. Merciless. In the center of it all a sole figure stood. Basking in the chaos and suffering of the innocent.
His maddening laughter pierced through the screams and cries for mercy. He was enjoying every moment of this. As the invasion came to its height his laughter cut off and he turned to the only one not meant to be there. Her body froze in terror under his gaze. As he began his approach ice traveled through her veins. A wicked grin crinkled the skin around his amber eyes that glowed in the fire light.
She could do nothing more than hold back the bile rising in her throat. She knew exactly what she was witnessing. The twisted dreams of a deranged man. Somehow she has been thrown into his dreams many times since learning her own clan was one of his many targets."
