Unseen Academicals (Discworld 37)

'Were the orcs terrible creatures?' said Glenda.

'I think I can probably show you,' said Hix.

'This gentleman has already shown me the picture in the book,' said Glenda.

'Was it the one with the eyeballs?'

Glenda found the memory only too vivid. 'Yes!'

'Oh, there's worse than that,' said Hix happily. 'And I suppose you want the proof?' He half turned his head. 'Charlie?' A skeleton walked out through black curtains at the far end of the room. It was holding a mug. There was something curiously depressing about the slogan on said mug, which ran: 'Necromancers Do It All Night'.

'Don't be scared,' said Dr Hix.

'I'm not,' Glenda said, terrified to her insteps. 'I've seen the insides of a slaughterhouse. It's part of the job and, anyway, he's polished.'

'Thank you very much,' the skeleton articulated.

'But "Necromancers Do It All Night"? That's a bit pathetic, isn't it? I mean, don't you think it's trying a bit too hard?'

'It was hard enough to get that one made,' said Dr Hix. 'We're not the most popular department in the university. Charlie, the young lady wants to know about orcs.'

'Again?' said the skeleton, handing the mug to the doctor. It had a rather hoarse voice, but on the whole far less dreadful than it might have been. Apart from anything else, his bones were, well, apart from anything else, and floated in the air as if they were the only visible parts of an invisible body. The jaw moved as Charlie went on: 'Well, I think we've still got the memory in the sump 'cos, you remember, we called it up for Ridcully. I haven't got round to wiping it yet.'

'Memory of what?' said Glenda.

'It's a kind of magic,' said Hix loftily. He continued. 'It would take too long to explain.'

Glenda didn't like this. 'Let's have it in a nutshell, then.'

'Okay. We're now quite certain that what we call the passage of time is in fact the universe being destroyed and instantly rebuilt in the smallest instant of eventuality that it is possible to have. While the process is instant at every point, nevertheless to renew the whole Universe takes approximately five days, we believe. Interestingly enough - '

'Can I have it in a smaller nut?'

'So you don't want to hear about Houseman's theory of the Universal Memory?'

'Possibly the size of a walnut,' said Glenda.

'Very well, then, can you imagine this: current thinking is that the old universe is not destroyed in the instant the new universe is created, a process which, incidentally, has been happening an untold billion number of times since I have been talking - '

'Yes, I can believe that. Can we try for a pistachio?' said Glenda.

'Copies of the universe are kept. We don't know how, we don't know where, and it beats the hell out of me trying to imagine how it all works. But we're finding that it is sometimes possible to, er, read this memory in certain circumstances. How am I doing in terms of nut dimensions?'

'You've got some kind of magic mirror?' said Glenda flatly.

'That's it, if you want the size of a pine nut,' said Hix.

'Pine nuts are actually seeds,' said Glenda smugly. 'So, what you're saying is that everything that happens stays happened somewhere and you can look at it if you have the knowing?'

'That is a magnificent distillation of the situation,' said Hix. 'Which is incredibly helpful while at the same time inaccurate in every possible way. But, as you put it, we use a'¨Cand here he gave a little shudder¨C'magic mirror, as you put it. We recently looked at the battle of Orc Deep for the Archchancellor. That was the last known battle in which the race known as orcs were deployed.'

'Deployed?' said Glenda.

'Used,' said Hix.

'Used? And you can find something like that in the total history of everything there has ever been?'

'Ahem. It helps to have an anchor,' said Hix. 'Something that was present. And all I am going to tell you, young lady, is that there was a piece of a skull found on that battlefield, and since it was a skull that firmly puts it into the responsibility of my department.' He turned to the Librarian. 'It's okay to show her, isn't it?' he said. The Librarian shook his head. 'Good. That means I can do it, then, under university statute. A certain amount of surreptitious disobedience is demanded of me. We have it set up on an omniscope. Since my colleague is so certain that I should not be doing this, he will not mind if I do. It's only a very brief fragment of time, but it did impress the Archchancellor, if impress is the right word.'
