Why wasn't miggery sow afraid of the dungeon?

Miggery Sow wasn't afraid of the dungeon because she had endured much worse in her life, including a harsh upbringing and mistreatment by her family. The dungeon, with its darkness and confinement, was less intimidating to her than the emotional and physical abuse she had faced. Additionally, her simple and naive perspective allowed her to see the dungeon as a place of potential escape and adventure rather than a fearful prison.
