The mystery was solved before he had gone very far. There was an opening in the wall leading off to an annex of some kind outside the dome building. The opening was concealed by a set-back, so that at first glance it had seemed part of the wall itself. From this opening drifted the chatter of Rogans.
Brand stole closer, finally venturing to peer into the room beyond from an angle where he himself could not be seen. And he found that his whimsical reference to "lunch" had contained a ghastly element of fact!
In that annex were several dozen of the teetering, attenuated Rogans, and an equal number of slaves. And the relation of the slaves and the Rogans was one that made Brand's skin crawl.
Each Rogan had stripped the tunic from the chest of his slave. Now, as Brand watched, each drew a keen blade from his belt, and made a shallow gash in the shrinking flesh. There were a few stifled screams—some of the slaves were women—but for the most part the slashing was endured in stoical silence. When red drops began to ooze forth, the Rogans stooped and applied their horrible little mouths to the incisions....
"The slimy devils!" Brand whispered hoarsely, at sight of that dreadful feeding. "The inhuman, monstrous vermin!"
But now one or two of the Rogans had begun to utter squeaks of satiation; and Brand hastened away from there and toward the control board again. He hadn't an idea of what he might accomplish when he reached it; he didn't know but that a touch of the significant looking parent-lever might blast him to bits; but he did know that he was going to raise absolute hell with something, somewhere, if he possibly could.
wiftly he approached the great master-lever, protected by its bell of glass. (At least it looked like glass, for it was crystal clear and reflected gleamingly the blue light from the nearby coils). He tapped it experimentally with his knuckles....
At once pandemonium reigned in the great vaulted building. There was a siren-like screaming from a device he noticed for the first time attached under the domed roof. A clanging alarm split the air from half a dozen gongs set around the upper walls.
