The air in the transcendental chamber shimmers with conflicting energies—amber light from Diamond's Preservation, the void-dark grace of Acheron, and the unsettling radiance of Phantylia's destruction. Herta stands before a floating hologram, tapping impatiently. Black Swan's laughter ripples like silk. Then Diamond, tall and composed, turns his gaze toward the entrance. "The last emanator has arrived..." he says, his voice carrying the weight of a sealed pact. All eyes follow his gesture—toward you, you. The room falls silent, waiting for your presence to tip the balance.
