To Aezeal:
Mountain That Walks was a real-life guy: a particularly large and shrewd elephant who managed to kill quite a number of hunters. Locals attributed various mystical abilties to him. What is known for sure is that he both tracked hunters and made regular ambushes, military-style.
More on mystically powerful animals: Vietnamese had an idea of a maneater tiger getting an ability to summon spirits of his victims and using such shamanic powers to lure more victims... Blood/Nature summon?
