Lotho's mother was a member of the Proudheart family of halflings, but known for her kind heart. It was said that she had inherited the ancient blood of angels that ran in the family, and was herself an aasimar. She lived among her halfling family peacefully in the village of Rubyblossom.
His father was a bloodthirsty orc chieftain who attacked Rubyblossom, taking what he wanted ... and leaving his mother behind with a child.
Rather than leaving Lotho to the elements, she found a way to love him and raise him within Rubyblossom, learning the importance of community, peace, and freedom. Lotho grew to enjoy the simple work of farming, finding that it helped to quell the fury that he felt flowing through his blood.
One day, Rubyblossom was attacked by a traveling group of brigands. Lotho felt the divine call of Erastil and organized a defensive force, fighting the bandits off in the Battle of Fallowleaf Field. Though they fought off the enemy, he saw in the eyes of his family and friends that the ferocity he exhibited on the battlefield had frightened them.
At his mother's recommendation, he set out on a pilgrimage into the wider world, to learn more about his new powers and how to balance the light and the darkness within him.
