So far the alarm had not spread outside of the building and Jason bolted the door from the outside. By the time this was broken open and the confusion sorted out they would be clear of the buildings. There was no need for the lamp now and would only give him away. He blew it out and from the desert came a continuous and ear-piercing scream.
"He's done it," Jason groaned. "That's the safety valve on the steam engine!"
He bumped into Ijale and Mikah who were milling about confusedly in the dark, kicked Mikah again out of sheer malice and hatred of all mankind, and led them towards the worksite at a dead run.

They escaped unharmed mainly because of the confusion on all sides of them. The D'zertanoj seemed to never have experienced a night attack before, which they apparently thought this was, and did an incredible amount of rushing about and shouting. Matters were not helped by the burning building nor the unconscious form of Edipon that was carried from the blaze. All the D'zertanoj had been roused by the scream of the safety valve, that was still bleeding irreplacable steam into the night air, and there was much milling about.
In the confusion the fleeing slaves were not noticed, and Jason led them around the guard post on the walls and directly towards the worksite. They were spotted as they crossed the empty ground and after some hesitation the guard ran in pursuit. Jason was leading the enemy directly to his precious steam-wagon, but he had no choice. The thing was certainly making its presence known in any case, and unless he reached it at once the head of steam would be gone and they would be trapped. He leaped the still recumbent guard at the entrance and ran towards his machine. Snarbi was cowering behind one wheel but there was no time to give him any attention. As Jason jumped onto the platform the safety valve closed and the sudden stillness was frightening. The steam was gone.
With frantic grabs he spun valves and shot one glance at the indicator: there wasn't enough steam left to roll the meters. Water gurgled and the boiler hissed and clacked at him while screams of anger came from the D'zertanoj as they ran into the enclosure and saw the bootleg caroj. Jason thrust the end of a molotail into the firebox; it caught fire and he turned and hurled it at them. The angry cries turned into screams of fear as the tongues of flame licked up at the pursuers and they retreated in disorder. Jason ran after them and hastened their departure with another molotail. They seemed to be retreating as far as the refinery walls, but he could not be sure in the darkness if some of them weren't creeping around to the sides.
He hurried back to the caroj, tapped on the still-unmoving pressure indicator and opened the fuel feed wide. As an afterthought he wired down the safety valve since his reinforced boiler should hold more pressure than the valve had been originally adjusted for. Once this was finished he chewed at his oily fingernails since there was nothing else that could be done until the pressure built up again. The D'zertanoj would rally, someone would take charge, and they would attack the worksite. If they had enough steam before this happened, they would escape. If not—
"Mikah, and you, too, you cowering slob Snarbi you, get behind this thing and push," Jason said.
"What has happened," Mikah asked. "Have you started this revolution? If so I will give no aid...."
"We're escaping, if that's all right with you. Just I, Ijale and a guide to show us the way. You don't have to come—"
"I will join you. There is nothing criminal in escaping from these barbarians."
"Very nice of you to say so. Now push. I want this steamobile in the center, far from all the walls, and pointing towards the desert. Down the valley I guess, is that right, Snarbi?"
"Down the valley, sure, that's the way." His voice was still rasping from the earlier throttling, Jason was pleased to notice.
"Stop it here and everyone aboard. Grab onto those bars I've bolted along the sides so you won't get bounced off, if we ever start moving that is."
Jason took a quick look through his workshop to make sure everything they might need was already loaded, then reluctantly climbed aboard himself. He blew out the lantern and they sat there in the darkness, their faces lit from below by the flickering glow from the firebox, while the tension mounted. There was no way to measure time since each second took an eternity to drag by.
The walls of the worksite cut off any view of the outside and within a few moments imagination had peopled the night with silent hordes creeping towards them, huddling about the thin barrier of leather, ready to swoop down and crush them in an instant.
"Let's run for it," Snarbi gurgled and tried to jump from the platform. "We're trapped here, we'll never get away...."
