Local legend has it that Beinn Ghobhlach mountain in the Scottish Highlands was once home to a witch. Resentful of sharing the area with people, she planned to cast a spell that would destroy the surrounding forests, making the land uninhabitable.
Before she could unleash the destruction, an enraged god used his sword to split her and the mountain in half, saving the forests and the people who relied on them.
