The following account was recorded in the agent's log during your transmission: Rusted pipes crisscross the roots of an upside-down, kilometers-tall tree, its massive trunk pointing towards the core of the Earth, surrounded by the eternal twilight of a hollow, ice-encased asteroid. Umm, air is stale and thick with the smell of old grease, and I hear the hum of... an abandoned, cyclopean, electromagnetic catapult, its copper coils snaking through the tree's branches like metallic tendrils. Faint sparks illuminate the frozen surface as night falls, outside the asteroid's shell. Water slowly drips, echoing off the metal pipes, in the still, cold air.
