"Keep an eye on the engine and I'll be back as soon as I can," he said, jumping to the ground and loading on equipment.
"You want me to do what? Stay here with this devil machine? I cannot! It will burn and consume me—"
"Act your age, Snarbi, your physical age if not your mental one. This rolling junk pile was made by men and repaired and improved by me, no demons involved. It burns oil to make heat that makes steam that goes to this tube to push that rod to make those wheels go around so we can move, and that is as much of the theory of the steam engine as you are going to get from me. Maybe you can understand this better—only I can get you safely away from here. Therefore, you will stay and do as I say or I will beat your brains in. Clear?"
Snarbi nodded dumbly.
"Fine. All you have to do is sit here and look at this little green disk, see it? If it should pop out before I come back turn this handle in this direction. Clear enough? That way the safety valve won't blow and wake the whole country and we'll still have a head of steam."
Jason went out past the still-silent sentry and headed back towards the refinery station. Instead of a club or a dagger he was armed with a well tempered broadsword that he had managed to manufacture under the noses of the guards. They had examined everything he brought from the worksite, since he had been working in the evenings in his room, but ignored everything he manufactured as being beyond their comprehension. This primordial mental attitude had been of immense value for in addition to the sword he carried a sack of molotails, a simple weapon of assault whose origins were lost in pre-history. Small crocks were filled with the most combustible of the refinery's fractions and wrapped around outside with cloth that he had soaked in the same liquid. The stench made him dizzy and he hoped that they would repay his efforts when the time came, since they were completely untried. In use one lit the outer covering and threw them. The crockery burst on impact and the fuse ignited the contents. Theoretically.
Getting back in proved to be as easy as getting out, and Jason felt an unmistakable twinge of regret. His subconscious had obviously been hoping that there would be a disturbance and he would have to retreat to save himself, his subconscious obviously being very short on interest in saving the slave girl and his nemesis, particularly at the risk of his own skin. His subconscious was disappointed. He was in the building where his quarters lay, trying to peek around the corner to see if a guard was at the door. There was, and he seemed to be dozing, but something jerked him awake. He had heard nothing but he sniffed the air and wrinkled his nose; the powerful smell of water-of-power from Jason's molotails had roused him and he spotted Jason before he could pull back.
"Who is there?" he shouted and advanced at a lumbering run.
There was no quiet way out of this one so Jason leaped out with an echoing shout and lunged. The blade went right under the man's guard—he must never have seen a sword before—and the tip caught him full in the throat. He expired with a bubbling wail that stirred voices deeper in the building. Jason sprang over the corpse and tore at the multifold bolts and locks that sealed the door. Footsteps were running in the distance when he finally threw the door open and ran in.
