Base 14

Base 14 is a massive city/military base, built upon an unknown landmass a little ways from North America. It is widely regarded as the homeland of the Eternals, due to the fact that 3 of their bases on earth reside there and there are little to no bases elsewhere. Base 14 was built to last, and it's 10 foot thick concrete and darkmetal walls protected the city for centuries, but they had one flaw: Explosives

During the Siege of Base 14, a small resistance formed and fought the attackers off, forcing them to flee, but not before they ended up burning the city to the ground. A week later, the city fell because their supply line was cut off by the Rogues. They soon took the city for themselves, and tried to hunt down the remaining survivors of the city that escaped, known today as Resilients. One such survivor was a boy named Cody, and he's pretty important.

About a hundred years later, Cody led a large force to take the city back. He nearly died, and his army had fallen. He was imprisoned and was going to be executed. If not for the actions of a bot named Fossil, Cody would have died there.

Another century later, Cody retried his assault on the base, and succeeded, bringing the city back under his control. Cody is widely regarded as a hero for his bravery.
