I would awaken with a deafening roar, showcasing my immense size and power to instill fear in the hearts of the would-be thieves. Then, I would calmly address the adventurers, telling them tales of the countless warriors who have attempted to steal my treasure, only to meet their doom. I would offer them a chance to leave peacefully and preserve their lives, in exchange for abandoning their mission.

In doing so, I would make it clear that the consequences of their persistence would be dire, ultimately leading them to reconsider and abandon their quest for my treasure.
