InterWorld (InterWorld 1)

As you can maybe tell by the description, Jakon was one of my more distant cousins.

At the moment she and I, along with Josef Hokun and Jerzy Harhkar, were standing on one of the higher balconies of Base Town, taking a rare break from studies and watching a herd of antelope creatures thundering along a narrow river valley beneath us. It was noonish, and the ward fields had been relaxed enough to let the planet’s fresh cooling breezes blow through. I stood next to an Iigiri tree, weighted with clusters of orange-red berries. Before us were flower beds full of royal lilies, honeybush, jove blossoms and blue lotus. There were cycads, conifers and flowers that hadn’t existed on most Earths for millions of years. Their combined scents were enough to make me dizzy, especially after the dry filtered air below levels.

Base Town, like the three or four other domed floating cities across which the forces of InterWorld were spread, had no fixed locale—instead it floated, by a combination of magic and science, across the face of a world where humans were still finding tasty fleas on each other. It was like living in a perpetual tour of a planet-sized national park, vista after vista of spectacular natural beauty. We skimmed the top of forests that spanned half a continent, hung over a waterfall that would never bear the name Niagara, safely sat ringside and watched volcanic eruptions, tornadoes, floods. . . .

There were worse places to go to school.

We were moving east and about due for another phase shift. It happened right on schedule; as we watched, the world before us flickered, then seemed to melt away, flowing into a momentary glimpse of the In-Between’s psychotic landscape before we came back to reality. After the aurora faded we were floating over a barren tundra with the sun high overhead. I could see a herd of aurochs stampeding away and a handful of lugubrious mastodons methodically stripping a large willow tree. The air was colder, and I saw, in the distance, the twinkling cliffs of mountainous glaciers as they crept toward us, shining like icebergs in the sun.

Same valley. Different world.

We do tend to surprise the locals when we enter; that’s why we stick to prehistoric time lines. Less chance of discovery. It was all part of the security measures that InterWorld took to keep the Binary and HEX from finding them. The floating domed cities shifted at random among a cluster of several thousand Earths about halfway down from the Arc’s center. That’s why, even with my skills in Walking the In-Between, I needed help to find the particular world Base Town was on.

The help had come in the form of that strange little equation that Jay had drawn in the bloody sand. Like most of InterWorld’s stuff, it worked by a combination of magic and science.

{IW}:=O/8

wasn’t a mathematical argument, exactly, nor was it entirely a magical spell. It was a paradox equation, like the square root of minus one; a combinatorial abstract, a scientific statement created by magical means.

{IW}:=O/8

was a memetic talisman that each of us carried in our heads and nowhere else, and which allowed us to “home in” through the last few layers of reality to reach Base Town, wherever it was. It was a key, and you needed to be a Walker to work the lock. Flying ships powered by bottled undead Walker energy couldn’t do it; nor could spaceships cruising through the video Static of underspace, powered by deep-frozen 99 percent dead Walkers. You had to be a real live Walker carrying the key in your head for it to work, which made it virtually impossible for either of the empires to find InterWorld.

That was the theory, anyway.

All of which explained the sense of security that allowed us to feel comfortable being out in the open while the four of us quizzed one another for tomorrow’s exams: Basic Theories of Multiphasic Asymmetry in Polarized Reality Planes and The Law of the Indeterminate Trapezoid as Observed in the Ceremony of the Nine Angles.

Even after five months, the majority of the recruits were still pretty cold toward me. They didn’t leave me alone at my table in the mess hall anymore, but they weren’t exactly running to sit next to me; and while they spoke to me, and were civil, there was still a sense of reserve there I couldn’t ignore. I was one of them—I was them, and you can’t keep hating yourself. But you still don’t have to like yourself all the time. So if I was never going to be Mr. Popular, well, I’d learned to deal with it. The three alternate versions of myself—the term our lecturer in Levels of Reality 101 used was “para-incarnations”—who were with me up on the deck were the closest I had to friends—which put them pretty much in the category of “not enemies.”

“Okay,” I was saying, “list the attributes that remain constant from plane to plane.”

“Um,” said Josef, and he scratched his nose. “All of them?”

“There are only four, Josef.”

Josef was from an Earth more dense than mine, which meant a higher gravitational field. Josef was built like a two-legged tank, and was probably stronger than any human being has a right to be. He explained it to me once—something about longer, wider tendon attachments, increased striated/smooth muscle ratio, and greater bone density. All I know is he was twice my height and almost strong enough to reach around behind and pick himself up by the seat of his pants.

“Symmetry, chirality, correspondence and, um.”

He looked like he could maybe beat a golem at a game of checkers, if somebody blindfolded the golem first. But as a matter of fact he was pretty smart—had to be, to keep up with all the other Joeys.

“Give up?”

“It’s not laterality, is it?” he asked without much enthusiasm.

“Yes,” I said. “It is.”

“My turn,” said Jerzy to me. “What are subliminal isorithms, and how do they apply to Walkers?”

“I know this one,” I said. “Wait, don’t tell me . . .”

Jerzy grinned. “Don’t worry—I won’t.”

Jerzy looked much closer to me on the evolutionary highway. The main difference between humanity on Jerzy’s world and on mine was that Jerzy’s people had feathers instead of hair. Oh—and the women gave birth to eggs instead of babies. That’s probably related. It was always startling to see Jerzy coming around a corner—he had pretty much my face, a bit sharper maybe in the nose and cheekbone department, but his eyebrows were soft gray down and his “hair” consisted of colorful featherlike growths about eight inches long. The tips were bright scarlet. Jerzy was a very b

right, quick, acerbic guy. He was probably the closest thing to a real friend I had in a few million Earths.

“An isorithm is something to do with how high things are, and subliminal isorithms are what allow Walkers to walk from one world to another without winding up twenty-five feet under the ground. It’s what keeps us at ground level wherever we go.”
