It was uncanny that this Wanderer should address him by name. Bert thrilled to a new sense of awe. "But," he objected, "my friends are in the hands of the spider men. You said we'd go to them. Good Lord, man, I've got to do it!" "You forget that time means nothing here. We will go to them in precise synchronism with the proper time as existent in that plane." * * * * * The Wanderer's intense gaze held Bert speechless, hypnotized. A swift dimming of the sphere's diffused illumination came immediately, and darkness swept down like a blanket, thick and stifling. This was no ordinary darkness, but utter absence of light--the total obscurity of Erebus. And the hidden motors throbbed with sudden new vigor. "Behold!" At the Wanderer's exclamation the enclosing sphere became transparent and they were in the midst of a dizzying maelstrom of flashing color. Brilliant geometric shapes, there were, whirling off into the vastness of space; as Bert had seen them in Tom Parker's instrument. A gigantic arc of rushing light-forms spanning the black gulf of an unknown cosmos. And in the foreground directly under the sphere was a blue-white disk, horizontally fixed--a substantial and familiar object, with hazy surroundings likewise familiar. "Isn't that the metal platform in my friend's laboratory?" asked Bert, marveling. "It is indeed." The mellow voice of the Wanderer was grave, and he laid a hand on Bert's arm. "And for so long as it exists it constitutes a serious menace to your civilization. It is a gateway to your world, a means of contact with your plane of existence for those many vicious hordes that dwell in other planes of the fifth dimension. Without it, the Bardeks had not been able to enter and effect the kidnaping of your friends. Oh, I tried so hard to warn them--Parker and the girl--but could not do it in time." A measure of understanding came to Bert Redmond. This was the thing Joan had feared and which Tom Parker had neglected to consider. The forces which enabled the scientist to see into the mysterious planes of this uncharted realm were likewise capable of providing physical contact between the planes, or actual travel from one to the other. Tom had not learned how to use the forces in this manner, but the Bardeks had. * * * * * "We travel now along a different set of coordinates, those of space-time," said the Wanderer. "We go into the past, through eons of time as it is counted in your world." "Into the past," Bert repeated. He stared foolishly at his host, whose eyes glittered strangely in the flickering light. "Yes, we go to my home--to what was my home." "To your home? Why?" Bert shrank before the awful contorted face of the Wanderer. A spasm of ferocity had crossed it on his last words. Some fearful secret must be gnawing at the big man's vitals. "Again you must trust me. To understand, it is necessary that you see."
