A massive modified trailer rolled out through the gates of the Underground City. Several cranes worked together to hoist the unconscious Hydra Emperor onto the trailer.
The vehicle slowly drove into the Underground City, following a dedicated transport route downward until it reached the training grounds of the Iron Blood Brotherhood.
