Dyson Sphere

At the question of translation, Hansen holds out a cylindrical device. "Brain wave decoder. Should work on any intelligent creature with a brain, and many without. Don't actually worry about breaching the hull. It's thick enough that a nuclear weapon probably wouldn't do the job. We've been crawling through it this whole time. Hold up! Indigenous life-form!" He points ahead to what appears to be a kitten, if kittens have dark green fur and three eyes. It's curled up in a small nest made from dried vegetation, some sort of leaves and vines that don't look familiar to any of you. The "kitten" appears to be asleep. Just beyond it is a grate, ending the passage. Light shines in through it.
