Deadspawn

Or ... perhaps he hesitated for another, far more elemental reason: something which warned him that with his small talents (small, yes, in the scale of a universe or parallel multiverses) he must not, dare not, usurp one of the Greater Talents of that Other whom men called God? History's necromancers, among which Janos had been a latecomer, had dared it, and where were they now? Had there been avenging angels before Harry, to put right the wrongs of these wizards? And if so, would there be one after him, to chastise him in his turn?

Harry had been the Necroscope, was becoming a vampire, and now would be a necromancer in his own right. How dare he seek out Pe

Perhaps the gears were already engaged, the wheels even now turning. Perhaps the Necroscope had already gone too far, disturbing the delicate balance between Good and Evil to such an extent that it now required radical readjustment. Had he simply become too powerful, which is to say corrupt? How did the old saying go: 'Absolute power corrupts absolutely'? Ridiculous! Was God Himself corrupt? No, for the maxims of men are like their laws: they apply only to men.

Such arguments were endless in the metamorphosis of the Necroscope's mind and body, until sometimes he thought he was mad. But when his thoughts were clear he knew that he was not mad; it was just the thing that was in him, altering his perceptions along with everything else.

And then he would remember how he used to be, determine that he must always be that way, and know that he hesitated only out of consideration for his friends among the dead. It was simply that he didn't want Trevor and Pe

As for God: if there was such a One (and Harry had never been sure) then the Necroscope supposed he must consider his talents God-given and use them accordingly. While he could.

Harry had spent a good deal of his time arguing, not least with himself. If a subject took his fancy - almost any subject - he would play word-games with himself to the point of distraction and delirium: a sort of mental masturbation. But it wasn't just himself he was jerking off; in conversations with the dead he was equally argumentative, even when he suspected that they were right and he was wrong.

Indeed, he seemed to argue for the sake of it, out of sheer contrariness. He thought and argued about God; also about good and evil, about science, pseudoscience and sorcery, their similarities, discrepancies and ambiguities. Space, time and space-time fascinated him, and especially mathematics with its inalienable laws and pure logic. The very changelessness of maths was a constant joy and relief to the Necroscope's changeling mind in its changeling body.

Within a day or two of returning from the Greek islands he had used the instantaneous medium of the Möbius Continuum to go to Leipzig and see (speak to) August Ferdinand Möbius where he lay in his grave. Möbius had been and still was a great mathematician and astronomer; indeed he was the man whose genius had saved Harry's life on several occasions, again through the medium of his Möbius Continuum. But while Harry's primary purpose in visiting Möbius was to thank him for the return of his numeracy, instead he ended up arguing with him.

The great man had happened to mention that his next project would be to measure space, and as soon as the Necroscope heard this he threw himself headlong into an argument. This time the argument was 'Space, Time, Light and the Multiverses'.

Won't 'Universe' suffice? Möbius had wanted to know.

'Not at all,' Harry had answered, 'because we know there are parallels. I've visited one, remember?' (And East German students with their notebooks had wondered at this peculiar man who stood by a dead scientist's tomb muttering to himself.)

Very well then, let's concentrate on the one we know best, Möbius had been logical about it. This one.

'You'll measure it?'

I propose to.

'But since it's constantly expanding, how will you go about it?'

I shall stand at its outermost rim, beyond which there is nothing, transfer myself instantaneously through the universe to the far rim, beyond which there is likewise nothing, and in so doing measure the distance between. Then I shall transfer myself instantaneously back here and perform the same experiment exactly one hour later, and again an hour after that.

'Good!' Harry had answered. 'But ... to what purpose?'

(A sigh.) Why, from that time forward - and whenever I require to know it - a correct calculation of the size of the universe will be instantly available!

Harry had stayed grudgingly silent for a moment, until: 'I too have given the matter a little thought,' he said. 'Though purely on the theoretical level, because the physical measurement of a constantly changing quantity seems rather fruitless to me. Whereas to understand what is happening, how and to what degree the age of the universe is tied to its rate of expansion - a constant, incidentally - and so forth, seems so much more satisfying.'

(An astonished pause.) Oh, indeed! And Harry had almost been able to see Möbius's eyebrows joining in a frown across the bridge of his nose. 'You' have thought about it, have you? Theoretically, you say? And might I inquire as to 'your' conclusions?

'You want to know all about space, time, light and the multiverses?'

If you've the time for it! Möbius had been scathing in his sarcasm.

To which the Necroscope had answered: 'Your initial measurement will suffice; no other is necessary. Knowing the size of the universe - and not only this one, incidentally, but all the parallels, too - at any given moment of time, we will automatically know their exact age and rate of expansion, which will be uniform for all of them.'

Explain.

'Now the theory,' said Harry. 'In the begi

Eh?

'Do you disagree?'

The universe was expanding at the speed of light?

'Actually, at twice the speed of light,' said Harry. 'That was the essence of your problem, remember, which sparked the return of my numeracy? Switch on a light in space and a pair of observers 186,000 miles away from it on opposite sides would both see its light one second later, because the light expands in both directions. Now, do you disagree?'

Of course not! The Primal Light, as any light, must have expanded just as you say. But... the universe?

'At the same speed!' said Harry. 'And it still is expanding at that speed.'

Explain. And make it good.

'Before the light there was nothing, no universe.'

Agreed.

'Does anything travel faster than light?'

No - yes! We can, but only in the Möbius Continuum. And I suppose thought is likewise instantaneous.

'Now think!' said Harry. The Primal Light is still travelling outwards, expanding on all frontiers at a constant speed of 186,000 miles per second. Tell me: does anything lie beyond those frontiers? And I do mean any thing?'

Of course not, because in the physical universe nothing travels faster than light.

'Exactly! Wherefore light defines the extent - the size -of the universe! That's why I called it the universe of light. A formula:
