"Yes. Such a design is like a translation from another language. In a way, it's what you're trying to understand by doing this verification web. This form characterizes a concept in much the same way that a math equation expresses physical attributes, such as an equation expressing the ratio of the circumference of a circle to the diameter. Emblematic forms can be a kind of language, too, the way mathematics is a form of language. They both are able to reveal something about the nature of things."
Zedd patiently smoothed back his hair. "You see emblems as a form of language?"
"In a way. Take the Grace underneath Nicci, for example. That's an emblem. The outer circle represents the beginning of the underworld while the inner circle represents the limits of the world of life. The square separating them represents the veil between those worlds. In the center is an eight-pointed star, representing the Creator's Light. The eight lines radiating out from the points of that star all the way out through the outer circle represent the gift carried from Creation all the way through life, across the veil, and beyond, into death. The whole thing is an emblem; when you see that emblem, you see it as a whole concept. You might say that you understand the language of it.
"If, during the casting of a spell, someone with the gift doesn't draw the grace correctly — hasn't spoken the language correctly — it won't work as intended and might even cause trouble. Say you saw a Grace with a nine-pointed star, or with one of the circles missing, wouldn't you know it was wrong? If the square representing the veil was drawn incorrectly, then under the right circumstances it could even theoretically breach the veil and allow the worlds to bleed together.
"It's an emblem. You understand the concept it represents. You know what it should look like. If it's drawn wrong, then you recognize it as wrong."
When the flashes of lightning flickered to a stop, the room felt forsaken in the weak light of lamps. Distant thunder rumbled ominously up from the valley below.
Zedd, standing stock-still, studied Richard with more focus than he had been studying the verification web. "I've never looked at it in quite that way before, Richard, but I grant that you might have a point."
Nathan arched a brow. "He certainly does."
Ann sighed. "Perhaps."
Richard turned from their dour expressions back to the glowing lines. "This, right here," he said, gesturing, "is wrong."
Zedd stretched his neck to peer at the lines. "Let's just say for the sake of argument that you're right. What do you think it means?"
Richard's heart hammered as he made his way around the table, swiftly tracing lines through the spell. He used a finger, keeping it just clear of the lines of light, to track the primary pathways, the sweeps of the pattern, the fabric of the form.
He found what he was expecting. "Here. Look here, at this newly formed structure that has built up around these older, original lines. Look at the disordered nature of this new cluster; they're a variable, but in this emblem of lines it should all be a constant."
"Variable…?" Zedd sputtered, as if having thought he was following Richard's reasoning, had instead suddenly found that he was completely lost.
"Yes," Richard said. "It's not emblematic. It's a biological form. The two are clearly different."
Nathan wiped both hands back over his white hair as he sighed but remained silent.
Ann's face had gone crimson. "It's a spell-form! It's inert! It can't be biological!"
"That's the problem," Richard said, answering her point rather than her anger. "You can't have these kind of variables tainting what's supposed to be a constant. It would be like a math equation in which any of the numbers could spontaneously change their value. Such a thing would render math invalid and unworkable. Algebraic symbols can vary — but even then they are specific relational variables. The numbers, though, are constants. Same with this structure; emblems have to be constructed of inert constants — you might say like simple addition or subtraction. An internal variable corrupts the constant of an emblematic form."
"I don't follow," Zedd admitted.
Richard gestured to the table. "You drew the Grace in blood. The Grace is a constant. The blood is biological. Why did you do it that way?"
"To make it work," Ann snapped. "We had to do it that way in order to initiate an interior perspective of the verification web. That's the way it's done. That's the method."
