Military action
After fighting off the N.E.R.V. assaults, the remaining Guardians realised that they were alone. The Beast had convinced the rest of Tantalus that it didn't exist while simultaniously it manipulated them into doing its bidding. To counter this, and build support for resupply, the Guardians produced and sold the drug Mithril. This made them wealthy, and they used that wealth to fund rebellion in the Districts to weaken the hold of the Beast. Eventually the Guardians became the hidden power behind one of the largest Cartels in Tantalus, and even reached out to Stormport in the Graveyard. They recruited support for anti-corporate terrorist actions aimed at weakening the hold of the Beast, while simultaniously seeking ways to reinforce the Guardians still holding Nemea. This over-reach was exploited by the Beast, who infiltrated the Guardians extended operations and toppled them. The massive 'criminal' organisation the Guardians had built to fund revolution fell rapidly and splintered into dozens of ignorant gangs. The Guardians withdrew once more to Nemea. The Beast had won the cold war.
