Like Abyss City, Aurora City was one of the major cities surrounding the Ludendorff family's headquarters at Throne City. It was even larger than Abyss City, and its military strength was greater too. However, its strategic position was not quite as critical as Abyss City's.
Nonetheless, the Ludendorff family had their own considerations for this. If the worst came to pass and Throne City fell or was overrun, the Ludendorff family's base of operations could temporarily relocate to Aurora City and start fresh.
As the King of the Wastelands, the Ludendorff family had spent years rolling through rebellions and wars, and they understood perfectly well the wisdom of having multiple backup plans.
'Once I'm back in the city and everything's sorted out, we'll coordinate with the main family base and attack Abyss City from both sides. I'm definitely going to take Andrew's head!' Ramon thought viciously.
With Throne City's forces added to the mix, Andrew and Abyss City would fall for sure.
