Tarrasque attack ( D&D)

The tarrasque was the most terrible creature known to inhabit the Prime Material Plane. It was created by the primordials as a weapon of destruction during the Dawn War, with the purpose of undoing the stability instilled in the world by the gods so that the primordials could remake it. Fortunately, the primordials created only one tarrasque, which slumbered within the world's core.[9] No one could predict when it would next awake. (extracted form the Forgotten Realms Wiki).
