Phssthpok sat dreaming in his disaster couch.

The cabin’s attitude controls were beneath his left hand. When he was hungry, which happened once in ten hours, his knobby hand, like two fistfuls of black walnuts strung together, would reach into a slot on his right and emerge with a twisted, fleshy yellow root the size of a sweet potato. Terrestrial weeks had passed since Phssthpok last left his disaster couch. In that time he had moved nothing but his hands and his jaws. His eyes had not moved at all.

Before that there had been a period of furious exercise. It is a protector’s duty to stay fit.

Even a protector with nobody to protect.

The drive was steady, or enough so to satisfy Phssthpok. The protector’s knotted fingers moved, and the heavens spun about him. He watched the other bright light float into the porthole. When it was centered he stopped the rotation.

Already brighter than any star around it, his destination was still too dim to be more than a star. But it was brighter than Phssthpok had expected, and he knew that he had let time slip away from him. Too much dreaming! And no wonder. He’d spent most of twelve hundred years in that couch, staying immobile to conserve his food supply. It would have been thirty times that but for relativistic effects.

Despite what looked to be the most crippling case of arthritis in medical history, despite weeks spent like a paralytic, the knobby protector was instantly in motion. The drive flame went mushy; expanded; began to cool. Shutting down a Bussard ramjet is almost as tricky as starting one. At ramjet speeds the interstellar hydrogen comes on as gamma rays. It would have to be guided away by magnetic fields, even if it were not being burned as fuel.
