Nyssa forced into robotic transformation

Lin Futu stands ready as Nyssa is brought in by hoplites and forced into a cubicle where technicians strap her in. A cold metal helmet descends over her head, sealing the conversion helmet in place as the transparent door slides shut. A sterile white light bathes the chamber, signaling the start of the Urbankan ritual. Lin Futu orders the process to continue without interruption, his five-minute countdown marking the irreversible binding of Nyssa’s mind and body into Monarch’s robotic duplicate. The moment encapsulates the Urbankans’ systematic eradication of individuality in service of their godlike vision, setting Nyssa up as the first forced vessel of their conquest.
