The Mulhorandi put his hand to his chin, thinking. "Dalrioc returned before he was supposed to and slew Brennan? Dalrioc's temper is quick, but what offense did Brennan offer to merit this response?"
Oriseus scowled. "One novice more or less is no loss, but I don't care for improvisation. I will look into this myself, I think." He wheeled and stalked out of the chamber, leaving Helrios to consider the frozen corpse.
Aeron did not hesitate. He reached down with one hand to take Baillegh by her collar and caught Melisanda by the arm with the other. As the door swung shut, he pulled them through and into the hallway beyond. Oriseus turned right to speak to the students and masters who awaited him; Aeron turned left and pulled Melisanda toward the servants' passages. Hoping that no one would notice a single door opening by itself, he slipped into the narrow hallway paralleling the main corridor and made his way to the servants' exit. He and Melisanda stumbled together as they blundered down the steps and out into the courtyard, unable to see their own feet.
"Aeron, look." Melisanda's voice whispered in his ear. Her voice was sick with fear. "The sky, it's all wrong."
He glanced up. Faint streamers of purple light twisted through the sky, each meeting over the tower. There were seven of them, arrowing toward the center from distant points spaced equally on the horizon. It's the magic trapped by the outlying shrines, Aeron realized. All the magic of Chessenta, channeled to this one point! But now it's visible in the real world. Beside him, Baillegh whimpered softly. Aeron watched for a long moment, his breath caught in his throat. "The flow of magic wasn't visible before."
"Do you remember what Oriseus said in the Council Chamber? About assembling the students and novices at dusk? Oriseus must be close to finishing his spell."
"I think you're right," Aeron said. "We're running out of time."
* * * * *
They found each of the library's doors locked and sealed with heavy chains. Aeron circled the building again, double-checking each entrance, but all had been secured against intrusion.
"Great." Aeron returned to the side door they'd first tried. "I have a spell that might disarm any magical traps here and open the door, but I'll lose my spell of invisibility if I cast it."
"Go ahead. I'll keep watch," Melisanda said. "At least we don't have to worry about anyone inside if Oriseus has decided to keep the other wizards out of here."
Casting a nervous glance around the quadrangle, Aeron waited to make sure that no one was in sight before muttering the spell of opening under his breath. He quickly slipped inside, holding the door until Melisanda and Baillegh brushed past, and quietly shut it. As far as he could tell, no one had spotted them.
He locked the door behind them, and turned to survey the vast stacks of books that towered in the gloomy chamber. The library's great windows were shuttered and secured, and it took a long moment for Aeron's eyes to adjust. Everything was covered with a fine layer of dust, indicating months, perhaps years, of disuse. But the rows of heavy tomes, scroll racks, atlases, and grimoires all seemed intact.
"What are we looking for?" Melisanda asked.
"The scrolls of Madryoch," Aeron said. "If they're here, they'll be hidden in an unmarked tube, with a scroll describing alchemical processes covering them."
"Wouldn't Oriseus have them, if they're that important?"
"Maybe, if he found them." Aeron allowed himself a small smile. "Five years ago, I hid them before I left my room. I'm hoping that Oriseus, or whoever it was who searched through my belongings, simply returned my books and scrolls to the library."
Deliberately, Aeron moved over to a scroll rack, pulled out the first unmarked case he found, and checked its contents. It was a text on Rashemite genealogy. He started to cap and replace it, then decided that time was more important than neatness. He dropped the case to the floor with a soft clatter and pulled out the next one, moving faster. At least I'll be able to see where I've been already, he thought, discarding the case. Melisanda gave him a startled look, but with a snort she copied his more direct approach, until the air seemed heavy with dust kicked up by scrolls clattering on the floor. Baillegh prowled around the library, her hackles stiff; Aeron guessed that the hound sensed the wrongness in the air and interpreted it as a threat.
It took half an hour before Aeron found the scroll he sought. "Melisanda!" he called. "I think this is it." Licking his lips, he carried it over to a nearby table and emptied out the scroll. Impatiently he brushed away the dry old alchemical treatise.
Underneath, a musty scroll of papyrus pages stitched side-to-side waited, covered with sinister whorls and runes. Brushing her hands against her skirt, the Chondathan sorceress moved closer and peered down at the ancient text.
"It's the same writing as the inscription on the Shadow Stone," she breathed. "You can make sense of this?"
"I think so." He drew the scrap of parchment from his belt pouch and laid it beside Madryoch's text. Carefully, he transcribed the Shadow Stone inscription from the meaningless marks of Madryoch's cipher into ancient Rauric, using the key he'd hidden in the Chants. It was not a long passage, and after a moment he straightened up, examining his work.
"What does it mean?" Melisanda asked, breaking the silence. "I know ancient Untheric and Thorass, but that doesn't seem familiar. Something about the powers of shadow, bound in stone?"
"That's pretty close," Aeron admitted. He leaned back from the table, looking up at Melisanda. Absently he noted that dusk was near; the gray daylight was fading outside the library's shuttered windows, and it was quite dim inside. "The old Imaskari sorcerers used knowledge they'd learned from creatures of immortal evil to record their spells. They weren't priests, really-they didn't draw their magic directly from the dark powers they served. They only used what they'd been taught to work their own sorcery. As best as I can tell, this inscription is a magical seal or bond, the keystone of an enchantment that focuses or channels the Shadow Stone's power."
"Just as we might seal a door or strengthen a tower by inscribing it with words of power," Melisanda observed.
"Exactly. The ancient sorcerers couched their invocations in different terms, but the principle is the same." Aeron stood and paced away from the table, rubbing his hands together. "So how can we use this to undo Oriseus's spell?"
"Magical writings can be erased," Melisanda pointed out. "I know several counterspells and abjurations to neutralize or destroy signs, wards, and glyphs-"
"But if you forged your counterspell from the Weave, the Shadow Stone would merely absorb it," Aeron broke in. "I'd have to craft the counterspell from shadow-magic. It may be that the stone wouldn't cancel a spell made from its own substance."
"Do you know a spell of erasure?"
"No, I don't have one prepared." Aeron swore viciously. "And Dalrioc took my spellbook when he chained me in the shadow shrine. Damn!"
Melisanda slumped against the wall, tears in her eyes. "My spellbook was taken as well. So close-"
Aeron slumped to the floor, grimacing in defeat. He leaned back against the crooked bookshelves, trying to think of a way to get at some student or master's spellbook in order to borrow the spell he needed. Wizards guarded their spellbooks well. It would be dangerous, but what choice did they have? Time was short. Baillegh pressed her nose against his face as if to console him. He scratched her neck and looked down into his lap, considering the best choice for his desperate effort.
