Overture of Dark Magic and an Unexpected Alliance

Since Ares returned from Dumbledore's office, Tom Riddle felt as if an invisible thread had tightened on his nerves. On the surface, Ares was acting as usual, but Tom caught his occasional absentmindedness and the elusive, complex emotions flashing deep within his heterochromatic eyes. These subtle changes gnawed at Tom's heart like ants, deepening his insecurity. Dumbledore's gaze, Peverell's scrutiny, and Ares's attraction, which seemed on the verge of slipping from his control at any moment... He had to do something; he needed an absolute safeguard that no external force could shake.

The ancient tome about Horcruxes in the restricted section had become his bible. He was no longer satisfied with theoretical research and began frantically searching for information on the ritual's specific steps, required materials, and suitable vessels. He wandered the castle like a phantom in the dead of night, using the Spyglass's sensitivity to powerful magical traces (he lied and claimed it was his detection ability) to search for places that might hide ancient, powerful items filled with negative energy—perfect vessels to hold fragments of his soul.

His paranoia and growing dark aura even affected their small circle. Avery and Rosier became more silent and submissive, looking at Tom with a trace of instinctive fear. Even Abraxas Malfoy had privately expressed a veiled concern to Ares, "Tom has been... overly focused on certain areas lately."

Ares knew this clearly but couldn't stop it. Every attempt to pull Tom back into the "safe" zone only invited Tom's colder scrutiny and the unspoken question, "Don't you understand me either?" He felt like he was standing on the edge of a chasm, watching Tom drift further away on the other side, while the bridge connecting them was becoming precarious.

Just then, Katarin Vol, the exchange student from Durmstrang, once again proved her worth. During a practical Dark Magic Defense class, Billius Black of Gryffindor, in a sparring match, attempted to disrupt Katarin with a provocative gesture he'd seen in his family's library, one he hadn't fully practiced. This gesture carried an extremely insulting meaning in some Eastern European dark magic traditions.

Katarin's eyes instantly turned as cold as the Siberian wind. She didn't use her wand, nor did she cast a spell. She simply raised her hand, fingers slightly spread, and an invisible, icy surge of magic lashed out like a whip towards Billius. Billius cried out and stumbled back, a faint red mark appearing on his face. Although the physical damage was minor, the cold malice contained within the magic instantly turned his face pale.

"At Durmstrang," Katarin retracted her hand, her tone flat but with a chilling coldness, "we don't use childish tricks. If you want to provoke, do it with strength."

The entire room fell silent. Even the Professor was stunned for a moment before stepping forward to check on Billius. Tom stood to the side, his eyes gleaming with admiration. Katarin had displayed not only power but also a style of action that was efficient and ruthless, something he greatly appreciated.

After class, Tom approached Katarin proactively.

"A very clean and efficient technique, Miss Vol," Tom praised, his tone carrying an equal measure of admiration.

Katarin appraised him, her dark eyes assessing, "Thank you, Mr. Riddle. It seems Hogwarts isn't entirely filled with hothouse flowers."

"Of course not," Tom smiled. "Some people are born for a wider, more... real stage. I believe we can find common ground."

He extended an invitation, not to join his burgeoning "inner circle," but a more flexible alliance based on shared interests and mutual recognition of strength. He hinted that certain "conservative" forces at Hogwarts (implying Dumbledore) were stifling the growth of truly talented individuals and mentioned he was "exploring" some "ancient paths" that could break these limitations.

Katarin was clearly intrigued by the picture Tom painted. She was accustomed to a power-based hierarchy at Durmstrang, and Tom's ambition and displayed potential aligned perfectly with her pursuit of strength.

"It sounds interesting," she didn't commit immediately, but her attitude was clear. "I hate boredom and constraints."

Tom knew he had found a potential, powerful executor. Katarin's background and modus operandi were perfectly suited for handling matters... that were inconvenient for him to handle himself.

However, just as Tom thought things were moving in his desired direction, an unexpected incident occurred. One evening, as Ares was researching alone in the library, he encountered Katarin again. She seemed to have just finished a discussion with the Charms professor about Eastern European magical systems.

"Phoenix," Katarin called out to him, her tone direct, "You and Riddle, what are you researching?"

Ares's heart grew wary, but his expression remained calm. "Many things. Magic is always full of unknowns, isn't it?"

Katarin stepped closer, her sharp gaze sweeping across his face, especially his heterochromatic eyes. "I can sense an... unusual magical fluctuation around you. Not just powerful, but also an ancient, restrained force." She paused, lowering her voice, "Riddle is chasing something dangerous, and you... you're trying to balance it, aren't you?"

Ares's heart sank. Katarin's perception far exceeded his expectations. She not only sensed Tom's involvement with dark magic but also vaguely perceived his role.

"I don't know what you're talking about, Miss Vol," Ares maintained his composure.

Katarin smiled, a smile devoid of warmth. "No need to be nervous. I just want to say that sometimes, even the brightest light needs shadows to make it stand out. And sometimes, the shadows themselves may have their own will." She gave Ares a meaningful look and turned away.

These words struck Ares like an alarm bell. Katarin was not a simple pawn that Tom could casually manipulate. She was extremely perceptive, had her own judgment, and seemed... more interested in the "shadows" Ares represented beneath Tom's "light."

Tom accelerated on his path of darkness, the unexpected variable Katarin intervened with her own agenda, and Dumbledore's gaze remained like a shadow. Ares stood in the eye of the storm, feeling the ropes holding everything together snapping one by one. Tom was preparing a forbidden ritual, Katarin was watching intently, and the secret of his own bloodline was like a volcano about to erupt. The end of the second year was brewing a storm that could change everything.
