Fort Ironhide, also known as the Iron Hill, was a castle in the Northlands during Dragonhollow's Third Era. It was built by and served as the primary residence of FlyingPokemon. Fort Ironhide was built at the border of the Northlands where a sprawling savannah met desert, not far from where Eris had placed a magical barrier that encircled the entire region. Perched upon several hills of different heights, the fortress served a strategically important role during the Northham Wars. It was next to Zen's Nirvana estate.
