Unwanted

there was this tiger warlord. He wanted to rule all the realms, so he kidnapped three princesses. A dragon, a wolf, and a demon. He, well, he force fed them fertility potions, raped them, and as soon as they gave birth, killed them(or so we are to believe). The tiger/dragon hybrid was Aiden Moonclaw, who was trained in elemental magic and potions. The wolf hybrid, Carla Beastpaw, was trained in animal training and wilderness survival techniques. And the tiger/demon was named Asthore Bloodfang, though her friends call her Ash. She was trained in dark arts and seduction.

When they turned 16, they found out about their mothers' fate, and when their father gave them the option to join his military forces, they bluntly refused, and were promptly thrown into the dungeons. Using their joined skills, they escaped, and said that they'd go to their home countries to train, and return when they turned 20
