"What do you mean?" I mumbled through a bone, hoping he would elaborate.
"You're a lot more confident with your magik. You'd better watch your controls, though. You had enough energy in that pentagram to fry anything that bumped against it."
"I guess I'm still a bit worried about the assassins."
"Relax, kid. It's been three days since we set 'em up in that ambush of Quigley's. Even if he didn't stop 'em, they'll never catch up with us now."
"Did I really summon up that much power?" I urged, eager for praise.
"Unless you're actually engaged in magical battle, wards are used as a warning signal only. If you put too much energy into them it can have two potentially bad side effects. First, you can draw unnecessary attention to yourself by jarring or burning an innocent bystander who blunders into it. Second, if it actually reaches a magical opponent, it probably won't stop him; just alert him that he has a potentially dangerous foe in the area."
"I thought it was a good thing if I could summon up lots of power."
"Look, kid. This isn't a game. You're tapping into some very powerful forces here. The idea is to strengthen your control, not see how much you can liberate. If you get too careless with experimenting, you could end up helpless when the actual crunch comes."
"Oh," I said, unconvinced.
"Really, kid. You've got to learn this. Let me try an example. Suppose for a minute you're a soldier assigned to guard a pass. Your superiors put you on the post and give you a stack of ten-pound rocks. All you have to do is watch to see if anyone comes, and if they do, drop a rock on their head. Are you with me so far?"
"I guess so."
"Fine. Now it's a long, boring duty, and you have lots of time to think. You're very proud of your muscles, and decide it's a bit insulting that you were only given ten-pound rocks. Twenty-pound rocks would be more effective, and you think you could handle them as easily as the ten-pound variety. Logical?"
I nodded vaguely, still not sure what he was driving at.
"Just to prove the point to yourself, you heft a twenty-pound rock, and, sure enough, you can handle it. Then it occurs to you if you can handle a twentypounder, you should be able to handle a forty-pounder, or even a fifty-pounder. So you try. Then it happens."
He was getting so worked up I felt no need to respond.
"You drop it on your foot, or you pull a muscle, or you keel over from heat exhaustion, or any one of a hundred other things. Then where are you?"
He leveled an accusing finger at me.
"The enemy strolls through the pass you're supposed to be guarding and you can't even lift the original tenpound rock to stop them. All because you indulged in needless testing of idiotic muscle power!"
I was impressed, and gave the matter serious thought before replying.
"I see what you're saying, Aahz, but there's one flaw in your example. The keyword is 'needless.' Now in my case, it's not a matter of having a stack of ten-pound rocks that would do the job. I have a handful of gravel. I'm trying to scrounge around for a rock big enough to do some damage."
"True enough," Aahz retorted, "but the fact remains if you overextend yourself you won't be able to use what you already have. Even gravel can be effective if used at the right time. Don't underrate what you've got or what you're doing. Right now you're keeping the finder spear going, maintaining the wards, and keeping my disguise intact. That's a lot for someone of your abilities to be doing simultaneously. If something happened right now, which would you drop first?"
"Um...."
"Too late! We're already dead. You won't have time to ponder energy problems. That's why you always have to hold some back to deal with immediate situations while you rally your energies from other activities. Now do you see?"
"I think so, Aahz," I said haltingly. "I'm a bit tired."
"Well, think about it. It's important. In the meantime get some sleep and try to store up your energies. Incidentally, let the finder spear go for now. You can summon it up again in the morning. Right now, it's just a needless drain."
"Okay, Aahz. How about your disguise?"
"Hmm ... better keep that. It'll be good practice for you to maintain both that and the wards in your sleep. Speaking of which...."
"Right, Aahz."
I drew my acquired assassin's cloak about me for warmth and curled up. Despite his gruff manner, Aahz was persistent that I get enough sleep as well as food.
Sleep did not come easily, however. I found I was still a bit wound up over casting the wards.
"Aahz?"
"Yeah, kid?"
"How would you say my powers right now. stack up against the devils?"
"What devils?"
"The assassins that were following us."
"I keep telling you, kid. Those weren't Deveels, those were Imps."
"What's the difference?"
"I told you before. Imps are from Imper, and Deveels...."
"... are from Deva," I finished for him. "But what does that mean? I mean, are their powers different or something?"
"You'd better believe it. kid." Aahz snorted. "Deveels are some of the meanest characters you'd ever not want to tangle with. They're some of the most feared and respected characters in the dimensions."
"Are they warriors? Mercenaries?''
Aahz shook his head.
"Worse!" he answered. "They're merchants."
"Merchants?"
"Don't sneer, kid. Maybe merchants is too sedate a phrase to describe them. Traders Supreme is more like it."
"Tell me more, Aahz."
"Well, history was never my forte, but as near as I can tell, at one time the entire dimension Deva faced economic ruin. The lands suffered a plague that affected the elements. Fish could not live in its oceans, plants could not grow in the soil. Those plants that did grow were twisted and changed and poisoned the animals. The dimension was no longer able to support the life of its citizenry."
I lay, staring up at the stars as Aahz continued his tale.
"Dimension travel, once a frivolous pastime, now became the key to survival. Many left Deva, migrating singly or in groups to other dimensions. Their tales of their barren, miserable homeland served as a prototype for many religious groups' concept of an afterworld for evil souls.
"The ones who stayed, however, decided to use the power of dimension travel in a different way. They established themselves as traders, traveling the dimensions buying and selling wonders. What is common in one dimension is frequently rare in another. As the practice grew, they became rich and powerful... also the shrewdest hagglers in all the dimensions. Their techniques for driving a hard bargain have been passed down from generation to generation and polished until now they are without equal. They are scattered through the dimensions, returning to Deva only occasionally to visit the Bazaar."
"The Bazaar?" I prompted.
"No one can travel extensively in all the dimensions in one lifetime. The Bazaar on Deva is the place the Deveels meet to trade with each other. An off-dimension visitor there will be sore pressed to not lose o'er much, much less hold his own. It's said if you make a deal with a Deveel, you'd be wise to count your fingers afterward... then your arms and legs, then your relatives...."
"I get the picture. Now how about the Imps?"
"The Imps." Aahz said the word as if it tasted bad. "The Imps are inferior to the Deveels in every way."
"How so?"
"They're cheap imitations. Their dimension, Imper, lies close to Deva, and the Deveels bargain with them so often they're almost bankrupt from the irresistible 'fair deals.' To hold their own, they've taken to aping the Deveels, attempting to peddle wonders through the dimensions. To the uneducated, they may seem clever and powerful; in fact, occasionally they try to pass themselves off as Deveels. Compared to the masters, however, they're bungling incompetents."
