"And the Green Man just killed the man?" the young aristocrat asked.
"There are some things that have to be destroyed," Ms. Madison shook her head. "And the Terror was something that the world will never be ready for. The A-bomb is bad enough, imagine a weapon that could kill an entire army and leave no damage to property. The country that had the Terror would have been invincible."
The brunette nodded soberly.
"I guess you're right," she conceded, "but what if more countries had it?"
"The extinction of the human race," Ms. Madison replied. "The Terror gives the impression that a war with this weapon can be won. The moment the atom bomb was used, people realised how terrible it was, the Terror was more terrible. No-one would understand how terrible it was until it was too late."
"And the human race would be destroyed, or as good as," Lady Sylvia nodded. "So we take it on ourselves to keep it from humanity?"
"Who else is there?" Ms. Madison sighed. "Sylv, I've been in this longer than you, and I learned ages ago that there are some things in this world that must be fought, evils from the pit that should never escape. And when a person embraces those evils, sometimes it is necessary to destroy them."
Lady Sylvia made no reply. Again, all that could be heard was the thunder of the falls. But this time birdsong mingled with it.
