The deadly air of the enclosure was now overwhelming Zehru with swift and hideous death. He was literally rotting before Blake's horrified eyes, the gray-scaled skin sloughing off in streaming rivulets of pallid ooze, and the entire body contorting in what was obviously a death agony.
Sickened, Blake stepped back a pace or two. Zehru's tentacles feebly beat the ground around him, then suddenly one of the writhing arms blundered upon a thin cable running along the ground. Before Blake could spring forward to stop him, Zehru with a last surge of power ripped the fragile metal strand completely in two.
It was the Xollarian's dying effort. He slumped in a motionless, nearly liquescent heap. But that last blind blow at the Earthlings threatened to be a deadly one. The severed cable led to one of the black posts surrounding the enclosure. With the cable's parting an entire section of one of the gold-flecked barrier walls vanished. Xollar's deadly purple mists were already surging in.
Speed was the Earthlings' only chance now. Helen was as quick to realize the danger as was Blake. Side by side they started their mad race toward where the silver arch-gate loomed nearly a hundred yards away.
They had covered barely half the distance when the air around them began to show a definite tinge of purple. With the appearance of the purple hue there came a strange and swiftly increasing agony, a torturing vibration that seemed to be tearing every atom in their bodies asunder.
They were within ten yards of the arch when Helen fell. Blake grabbed her up in his arms and stumbled on. There was no longer enough oxygen in the air to even breathe. Blake's lungs were on fire. Every cell in his body seemed vibrating in unbearable torment.
It was all that he could do to struggle up on the low platform. He staggered across the space and under the arch. It took the last shred of strength in his tortured body for him to lift his hand and pull the black lever down into place.
Its action was instantaneous. The agony of the purple mists was blotted out in a surging wave of mighty force that swept Blake and Helen up and away through a Spaceless universe where black chaos reigned awesomely supreme. There was a long terrible moment of hurtling through distances inconceivably vast. Blake's brain reeled in nausea.
Then suddenly all motion ceased and everything was normal again. There was firm grassy ground under his feet and a cool breeze was blowing in his face.
