Pigeon's Milk.

The protagonist is a kind and brave boy who helps people fight evil. One day, a horseman arrived at the doorstep of an orphan’s house, asking for wine and oats for his horse. The house owner, unable to provide more than a dry flatbread, offered the horse hay instead of oats, which he used as bedding. The horseman was touched by the boy’s kindness and promised to reward him generously if he followed in his footsteps and helped others along the way.
