Badlands

The Badlands (also known as the Mobian Badlands) is a large region on the planet Mobius, specifically on Westside Island. It is located in the middle of the ruins of Mobotropolis (now referred to as Robotropolis) and the Westside Overland, with Fort Acorn being near the former, and the region itself not being that far from the Feral Forest, Mystic Cave, and is even nearby New Mobotropolis.

Prison Assault
At the time of the Great War in early 3220, the Overlander forces had a prison complex within the Badlands itself that was used to keep prisoners of war. One of these prisoners was Savanna Verdia Burns, who was captured in a covert operation, was held there for trying to enrage her husband Adex, along with Dr. Ivo Robotnik and Snively Robotnik for attempting to test a super weapon on live Overlanders.

After gathering some information of the prison's location, the Kingdom of Acorn's Royal Army was sent to attack the facility, suspecting that the prison was holding the Royal Wizard and kingdom's Warlord (at the time) in a rescue mission. The Royal Army forces were led by Adex and Amadeus, both of whom were promoted to generals beforehand, while receiving firearms from a ship after King Maximillian had temporarily uplifted the ban on guns for the rest of the war.

After fighting their way through Overlander trenches and even a large battle tank, the Royal Army had reached the complex and prepared to attack the facility. The prison's automated defenses however kept most of the Royal Army from reaching it's interior, even injuring Jules Hedgehog almost fatally. During the attack, only Adex was able to get inside and successfully disable the prison's defenses to allow the rest of the army to get in the prison.

While the Royal Army was unable to find the Royal Wizard and Warlord, Adex instead found Ivo Robotnik and Snively, who revealed they had vital information that the Kingdom could use to win the war. Trusting the two about their claims and not knowing of their plans, Adex set the two of them free, as they made it safely back to Mobotropolis, where their information would be vital enough to help the Kingdom win the war. Adex was also able to free his wife Savanna from captivity, learning of her pregnancy that she kept a secret from him while they returned home happily.

The Great War ended within a few months after the assault on the Overlander prison, which was suspected to be destroyed after the conflict ended.
