Man-Wol was named for the full moon that she was born under, that being what her name means. Her family hunted and fished, sticking to the forests away from other people and taught their daughter to avoid Spirits as this was the time before the Spirit Emperor. But one day, young Man-Wol with her bow at her side encountered another person in the wood. For a moment though, she had been certain what she saw was not a person but a bear. She spoke to them, uncertain at first, and learned that their name was Hakja. The two became fast friends, promising to meet again.
And they did. For months, Hakja and Man-Wol met in secret in the woods, talking and hunting together. Hakja had a talent for tracking and knowing the ways of the animals but Man-Wol was the far better shot. They also taught her about the plants of the forest, the ones that could heal and the ones that could harm.
One day, Man-Wol entered the forest alone as was her habit, but on the way her father warned her that he’d seen a bear in the area and taken a shot at it. Wary now, she kept her bow in hand and an arrow on the string. She heard a sound and froze as something large was coming near. She could spy the bear between the trees, moving quickly towards her. In a moment of terror, she loosed an arrow and caught it solidly… just as Hakja let go of that form and took on the appearance of a human again.
They fell backwards, the arrow protruding from their chest, and Man-Wol ran forward, her bow falling from her fingers to lay abandoned on the forest floor. Instead, it was the pouch of medicines at her waist that she reached for. Bandages, a knife, a poultice they had taught her to make.
When she was sure they would live, Man-Wol gathered her things to leave with tears on her cheeks only to hear Hakja calling her back. It had been an accident, they said. She need not take on guilt for that.
Still, Man-Wol couldn’t help but blame herself. So she took up a vow to never take up her bow again and to spend her days instead wielding only the mortar and pestle, the herbs in her pouch, and the knife that only cuts away the bad. Hakja stayed with her and the two wandered Goguryeo studying the plants that could be found and what they could be used to treat. And eventually, two became three as the pair started their own family.
The stories also say that one day, Man-Wol and Hakja came to the court of the Spirit Emperor to present their learnings and it was there they were given the gift of writing so their discoveries would never be forgotten.
