Ambassador 1 from the City State of Binding Light

One of two Ambassadors from the City State of Binding Light attended Earth Death aboard Platform One in the year 5,000,000,000. They wore robes with a floral pattern which distinguished them from their fellow ambassador. In the immediate aftermath of Earth Death, which resulted in the deaths of several guests due to the space station's defences being sabotaged by Lady Cassandra, the representative was seen alone.
