We slide the doorslide as a plunging wave of Physicals came and hurled themselves against it....

Then in a moment the big disc was slowly rising. From a bullseye window of the central turret we could see the raging little things as they dropped from the rim of the disc.

The ground slid slowly away beneath us. The sounds were shut off from us now. Mute, ghastly scene. We had only a brief glimpse of the glowing, wrathful monster. It palpitated, quivered in the midst of the carnage. Monster of the planet. Omnipotent ruler here. There were no humans running now. No human bodies were on the rocks. Nothing but crimsoned, noisome fragments with little shapes fighting over them.

The terrible scene in a moment dropped away, blurred and was gone so that there was just starlight here in the turret. The myriad stars of Interplanetary Space. And at the dark, rocky horizon of the planetoid the Earth was just rising, a great mellow crescent, beckoning us.
