When Durga first came to live with the God Adharma and begin her training to be a lord it was learning to take care of the palace horses that really helped her find peace, heal and adjust after the loss of her mother and the shift to a new, better life after years of struggle and abuse.
As she grew older her interest in horses spurned her to learn proper breeding techniques and now, as an adult and an establish lord with her own holdings she breeds some of the best horses around. Particularly war steeds. They are well known for their intelligence and train-ability and come to be highly sought after. It is the selling of steeds brings in much of the money that supports her lands.
Durga has her own personal stable where she keeps the best stock for her and her soldiers. These horses are never sold. She does however like to show them off on occasion.
