As betrayal turns into war and survival demands sacrifice, everyone plays a role in the grand illusion. Some will rise by deceiving, others will fall by trusting. But no one-not even the ones who started it all-will escape unscathed. Deception is not just a continuation. It's a descent. Deeper into the lies. Deeper into the love. Deeper into the blood-soaked truth.
