Cailin was born to a family of farmers on the outskirts of a small village in the Kingdom of Fife. She was always a strong and independent child, preferring to play in the woods with the boys rather than stay at home with the girls. When she was old enough, she began training with her father to become a warrior like him. She excelled at everything she did and quickly became one of the best warriors in the kingdom. She fought in many battles, always leading from the front and never backing down from a challenge. She gained a reputation for being fearless and unstoppable. One day, while Cailin was out training alone, she was attacked by a group of bandits. She fought them off easily, but one of them got away. This bandit happened to be the brother of a powerful warlord who ruled over a neighbouring kingdom. The warlord declared war on Cailin's kingdom in retaliation for his brother's death. Cailin led her kingdom's army into battle against the invaders and emerged victorious. This great deed cemented her place in history as one of the greatest heroes of her time.
