66 Duke Avenue, Mars Central City - this white baroque building at the corner of the crossroads is the headquarters of the Phantom Stream's main sect, the [Griffin Knight] Mecha Fighting Hall.
The gates of the Fighting Hall are arched stone gates, with six griffon reliefs sculpted on top of the doorframe. Above it, there is a mecha sculpture that bears a striking resemblance to a griffon. The sculpture's beautiful curves and the harmonious integration of its heavy and stable limbs with its defiant war eagle feathers make it the symbol that has stood in the Free World for a hundred years as the emblem of the Griffin Knight.
At this moment, however, the grand hall entrance stands desolate. The huge Fighting Hall sign has stopped its neon flashing, and the heavy black door is tightly shut. Passersby hurry past, and occasionally, a low sigh can be heard amid the crowd.
