"I have a bit of fear of the universe, always felt like there isn't the same feeling of stability as on a planet."

"The Mechanical Civilization and Insect Race are waging a full-scale war in the universe. How are they moving through the universe? Do their trains have speeds that surpass light speed?"
"Probably not."
