A sudden rush of heat flared in Cactus's chest, a possessive instinct gripping him. His eyes narrowed on the MudWing, Bog, hunched over the ancient scroll. This wasn't just some dusty relic; it felt like a key, and Bog was too close to it, too curious. Cactus's talons twitched, a protective urge coiling in his gut. Bog, sensing the presence, slowly lifted his head. His usually placid, scholarly face was drawn, etched with exhaustion. His eyes, dark and heavy, met Cactus's. Then, a flicker. A subtle shift in Bog's gaze, a knowing, almost desperate understanding that mirrored the unease churning within Cactus. It wasn't the wary look of a dragon caught trespassing. It was something deeper, a shared burden. Cactus felt a jolt of something akin to relief, quickly stifled by his ingrained caution. He wasn't alone. Another dragon felt it, too. This strange, insistent humming that had begun to infest his thoughts, his very bones. Bog cleared his throat, a dry rasp. "You hear it, too, don't you?" His voice was a low murmur, barely disturbing the quiet of the library. He didn't ask *what* Cactus heard, only *if* he did. Cactus simply nodded, a tight, unyielding movement. He didn't trust easily. His past had taught him to guard his vulnerabilities, to control every situation. But this hum… it was beyond his control, a relentless invasion. Bog sighed, a heavy, air-displacing sound. He pushed away from the scroll, its ancient script a silent witness. "It's… relentless," he admitted, his voice barely above a whisper. "And it's getting worse." He rubbed his temples, his brow furrowed. "At first, I thought I was simply overworked. Too many late nights, too much parchment dust." A wry, humorless smile touched his lips. "But it's not fatigue. It’s… something else." Cactus’s gaze dropped to the scroll for a moment, then back to Bog. "What exactly do you hear?" he pressed, his voice a low growl. He needed details, needed to piece together this fragmented puzzle. Bog shifted, leaning back against a towering bookshelf laden with scrolls and heavy tomes. Dust motes danced in the faint moonlight filtering through a high window. "It's not just a hum anymore," he confessed, his voice dropping further. "Sometimes, I hear… phrases. Fragmented. Distorted. Like whispers through thick water." Cactus felt a chill crawl up his spine, despite the academy's humid air. Fragmented phrases. That sounded far more insidious than a simple drone. It suggested intent, a message. A manipulation. "What kind of phrases?" he demanded, his scales prickling. His mind raced, connecting this new information with the strange pull he'd felt toward the scroll, the bizarre incidents around the academy. Bog closed his eyes for a moment, as if trying to recall a distant, unwelcome memory. "Difficult to make sense of," he murmured. "Obscure. Ancient-sounding. Words that… don't quite fit. And then… the urges." Cactus's jaw tightened. Urges. This was getting dangerous. His core wound, the fear of failing to protect, flared. This wasn't just a nuisance; it was a threat, a subtle poison seeping into the minds of dragons. "What urges?" he repeated, his voice sharper now, cutting through the library's quiet. Bog opened his eyes, a look of profound unease in their depths. "To go deeper," he explained, a shudder passing through his massive frame. "To explore the lower levels of the academy. Especially the old tunnels beneath the main hall. It feels… like a summons." His gaze darted around, as if expecting to see the source of the summons manifest. "I've found myself down there, more than once, without consciously deciding to go. Just… drawn. And the humming is strongest there. Almost vibrates through the rock itself." Cactus absorbed this, his mind working furiously. The lower levels. The old tunnels. He remembered the descriptions of the academy's ancient foundations, how it was built into the very heart of the mountain. A targeted phenomenon, then. Not random atmospheric noise. "And the phrases… they accompany these urges?" Cactus asked, trying to find a pattern. "Sometimes," Bog confirmed. "Mostly when I'm in those deeper places. It's like the hum opens a channel, and these words… these thoughts… slip through. They are not my own, Cactus. I know they aren't." His voice held a note of desperation now, a plea for understanding. "It's like someone is trying to plant ideas. Or… awaken something." Cactus paced a short distance, his tail lashing softly, stirring up dust. The implications were chilling. Someone, or something, was actively using this hum, directing it, shaping it. This wasn't a natural phenomenon. It was a weapon. He stopped, turning back to Bog. "Have you told anyone else? The queens? Any of the teachers?" Bog shook his head vigorously, his jowls quivering. "No. Who would believe me? They'd think I've gone mad. A MudWing scholar, hearing voices in the walls." He gave a humorless chuckle. "I tried to rationalize it, to find a scientific explanation. Ancient plumbing, geological tremors, anything. But it defies logic." "And the scroll?" Cactus asked, gesturing to the parchment. "Is it related?" Bog looked at the scroll again, a hesitant expression on his face. "I found it like this. Open. It speaks of ancient wards, forgotten magic, and a 'shadow that sleeps beneath the peak'. I thought… perhaps it was a legend, a metaphor. But now… with the hum… and the urges…" He trailed off, his eyes wide. "I was trying to find correlations. Any historical accounts of such a phenomenon. Anything that could explain this." Cactus knelt beside the scroll, his talons tracing the faded script. "A shadow that sleeps beneath the peak." That sounded ominous. It fit the narrative of a dormant threat, now stirring. His mind immediately went to the safety of the academy's students, of the fragile peace Queen Glory had worked so hard to forge. If this was a targeted attack, a manipulation, it could shatter everything. He looked at Bog, a grim understanding passing between them. They were both caught in this, unwilling participants in a mystery that threatened to unravel the very fabric of their world. Bog, with his scholarly insight, and Cactus, with his… unique ability to sense undercurrents, to charm, to protect. "We need to be careful," Cactus said, his voice low and serious. "If this is a manipulation, then whoever is behind it won't want us interfering. Especially if we start looking in the lower levels." Bog nodded, a newfound resolve hardening his features. "I agree. I've heard stories of strange disappearances in the academy's early days, dismissed as 'runaways' or 'accidents'. But if this hum has been active for centuries…" He shuddered again, the implication clear. The academy, a supposed haven of peace, might be built over a very active, very ancient threat. His gaze drifted to the darkest corner of the library, as if the shadow itself might materialize from the gloom. Cactus rose, his senses heightened, his every nerve alert. The hum, always present, now felt like a living thing, a coiled serpent within the mountain. "We need to gather more information. Quietly. Starting with those lower levels." He looked at Bog. "Can you map them? Any secret passages, hidden chambers?" Bog nodded slowly, his eyes alight with the scholar's thrill of discovery, mixed with genuine fear. "I have some old blueprints, dusty and incomplete. But yes, I can try. It will take time." "Time we might not have," Cactus muttered, his gaze fixed on the faint, rhythmic vibration he felt through the floor. He could almost feel the mountain itself breathing, a slow, sinister pulse. Just as Bog began to elaborate on the complexity of the academy's ancient subterranean structure, a distant, muffled shriek echoed from the academy's depths, followed by a heavy, grinding thud that rattled the library shelves, sending a wave of primal fear through both dragons.
