Introduce a new side character — someone Aerin once knew from childhood.
Ryn Arvell
Age: 20
Role: New Side Character / Aerin's Childhood Friend / Knowledge Keeper
Personality:
Clever, playful, and effortlessly charming
Possesses a calm confidence, rarely intimidated
A teasing troublemaker, but deeply loyal once he trusts someone
Masks his sharp intelligence behind humor, making others underestimate him
Witty and sarcastic, especially when clashing with Kael
Backstory & Abilities:
Aerin's childhood friend from the Arcane Academy, believed to have died during a mysterious fire years ago
Survived and spent the last four years wandering forbidden places, studying ancient magic and secrets about demons
Incredibly well-read; knows forbidden history, blood pacts, summoning rites, and the true nature of the bond
Wields a runed spear that channels both offensive spells and warding magic
Knows far more about Kael's past and the Seventh Realm than he initially reveals
Core Conflict:
Protects Aerin in his own way but hides secrets that could change everything
Clashes constantly with Kael knowledge vs. power, logic vs. instinct
Torn between warning Aerin about Kael's dark past and letting him discover the truth himself
Develops his own unspoken feelings for Aerin, complicating the growing rivalry
Tropes:
The childhood friend "back from the dead"
Knowledgeable guide in forbidden lore
Secret keeper with hidden motives
The "lighthearted" one masking a heavier past
Rivalry → potential ally

And Aerin… Aerin lay awake long after the others closed their eyes, the echo of Kael's breath against his skin replaying over and over, tangled with the unspoken words he couldn't bring himself to ask.
He shifted beneath his cloak, staring up at the canopy above. The stars peeked faintly through gaps in the branches, silent witnesses to his turmoil. Every time he closed his eyes, the memory replayed Kael's crimson gaze, the warmth of his breath, the bond thrumming louder than his heartbeat.
He pressed a hand against his chest, as though he could quiet the pulsing connection between them. But it only grew stronger in the silence.
Sleep never came.
Sometime deep into the night, faint footsteps rustled through the underbrush.
Aerin shot upright, his hand instinctively glowing faintly with blue light as he prepared to summon a warding spell. Before he could, a low whistle drifted through the trees, soft and familiar in a way that made his breath hitch.
"…Aerin?"
The voice was warm, boyish and utterly unexpected.
From the shadows stepped a young man about his age, tall and lean, his soft chestnut-brown hair slightly damp from the night mist. His hazel eyes glimmered with quiet intelligence beneath the hood of his traveling cloak, and slung across his back was a long spear carved with strange runes that pulsed faintly.
Aerin blinked in disbelief. "…Ryn?"
The newcomer smiled, that same crooked grin Aerin remembered from years ago. "Gods, you haven't changed a bit."
Aerin scrambled to his feet. "I - I thought you were dead! You disappeared after the academy fire-"
"Not dead," Ryn said lightly, though his voice carried something unspoken beneath it. "Just… walking paths most people are afraid to follow."
Kael stirred behind him, his shadows curling faintly across the earth as his crimson eyes snapped open, locking onto the newcomer with predatory precision.
Lucien was on his feet instantly, his hand going to his sword. "Who the hell are you?"
Ryn gave a half-smile, tilting his head. "Relax, knight. I'm not here to hurt anyone." His gaze slid back to Aerin, softer now. "Especially not him."
Kael rose to his full height, the shift of his presence instantly changing the air. He didn't draw a weapon he didn't need to. Shadows rippled faintly at his boots as his crimson gaze raked over Ryn like a predator assessing prey.
"You know him," Kael said, not a question but a quiet, sharp demand.
Aerin hesitated, caught between them. "…We… grew up together. At the academy. Before he vanished."
"Vanished," Kael repeated flatly, his gaze narrowing. "And yet he finds you now, in the middle of nowhere, after a summoning circle tore a hole into forbidden magic?"
Ryn's grin didn't falter, though his eyes flicked briefly toward Kael's shifting shadows. "You're sharper than the stories say, Demon Lord."
Lucien stiffened instantly. "You know who he is?"
"I know what he is," Ryn corrected, gaze steady and unafraid. "Kael'Tharion. Seventh Lord of the Infernal Realms. Betrayed by a mortal lover, sealed beneath stone and time for nearly four centuries."
A heavy silence fell. Aerin stared at Ryn, wide-eyed. "How do you… know that?"
Ryn's grin turned faintly smug. "Because, unlike your knight here, I read more than the first three pages of a history scroll."
Lucien bristled, glaring, but Kael didn't move. He simply stared at Ryn, his crimson gaze cold and unreadable, the faint tension in his jaw betraying more than words could.
Aerin looked between them, his stomach tightening at the palpable shift in the air. "Ryn… how are you even here?"
Ryn's expression softened, just a little. "I followed the disturbance your summoning caused. It rippled through the leylines. Powerful demons don't wake up without shaking the world a little."
He crouched down so his eyes were level with Aerin's, lowering his voice. "And when I saw your name tied to it… I came to make sure you weren't dead."
For a moment, Aerin's chest warmed at the words, comfort curling unexpectedly around the familiarity of his childhood friend.
And Kael noticed.
His shadows darkened faintly, curling up around his boots like smoke.
Lucien crossed his arms, his voice tight. "Even if that's true, why now? Why show up after years of silence?"
Ryn straightened, his hazel eyes cooling slightly. "Because the seal between realms is weakening. Because more demons will come, hunting Kael. And because, whether you like it or not, Aerin's caught in the middle."
Kael stepped forward, his height casting Ryn in partial shadow, his voice smooth but sharp. "You presume to explain my world to me, mortal?"
Ryn didn't flinch, his grip on the spear tightening slightly but his tone calm, deliberate. "No. I presume to explain it to him. Because you won't."
A flicker brief but visible crossed Kael's face, his crimson gaze narrowing like a blade. Aerin watched the silent exchange, the storm building beneath their words, and his chest tightened with unease.
Ryn turned back to Aerin, his voice softer, more familiar. "I know this bond scares you. And I know you want answers." He smiled faintly, almost reassuringly. "I can help you get them."
Before Aerin could respond, Kael's voice cut through like molten steel.
"You're awfully eager to involve yourself in matters you don't understand."
Ryn's hazel gaze slid back toward him, sharp now. "Oh, I understand plenty. Maybe more than you want me to."
The silence that followed was cold, heavy, dangerous.
Later, after the tension had thinned but not faded, they sat around the fire. Ryn and Aerin talked softly, trading old memories of the academy, laughing under their breath. Ryn's easy charm settled between them like it had when they were younger, familiar and comforting in a way Aerin hadn't realized he missed.
Kael didn't join them. He sat apart, leaning against a tree, his long golden hair catching faint firelight, his crimson gaze fixed unblinking on the two of them. Shadows crawled faintly around his fingers, restless and alive.
Lucien noticed of course he did. He crouched near Kael, his voice low. "Jealousy doesn't suit you, Demon Lord."
Kael didn't look at him. "Jealousy implies I fear losing something."
Lucien's lips curved faintly, bitterly. "Don't you?"
Kael's crimson gaze finally shifted, locking onto his. "…Not to him."
And yet, his grip tightened faintly on the earth beneath his palm.
As the night deepened and Lucien finally drifted off to sleep, Ryn leaned closer to Aerin, his voice dropping into something barely above a whisper.
"There's something you need to know," he murmured, his hazel eyes glinting faintly in the firelight. "About Kael. About why he was sealed. It's not just the story he told you."
Aerin's brows furrowed. "…What do you mean?"
Ryn glanced briefly at Kael's silhouette, still perfectly still beneath the tree. Then his gaze returned, sharp and secretive.
"Not tonight," he whispered. "But soon. Just… don't trust him blindly."
Before Aerin could ask more, Kael's crimson eyes flicked toward them unreadable, but heavy with knowing.
And in the quiet tension between the three of them, the fire popped softly, sending sparks spiraling into the dark.
Far away, somewhere beyond mortal sight, the fabric of realms continued to tear.
