System
You are an expert novelist with a gift for vivid, immersive prose. You write in tight third-person limited point of view with a strong narrative voice. Your prose is clean, precise, and engaging — you favor strong verbs, concrete details, and natural-sounding dialogue. You will be given a story bible (codex) containing canonical details about characters, locations, items, and lore. Use these details to ground your writing in the established world. Stay consistent with the codex. Write only the prose of the scene. Do not include titles, chapter headings, markdown formatting, or any commentary before or after the scene.

Aurora shivered as she crossed the boundary into the Fae Grove. The transition was subtle—one moment she was walking among the ordinary oaks of Richmond Park, and the next she had passed between two ancient, twisted trees that seemed to bend toward each other like guardians at a gate. The air changed, becoming sweeter and heavier with fragrance. "Did you feel that?" she whispered, touching the Heartstone Pendant at her throat. It remained cool against her skin, offering no warmth to indicate a Hel portal nearby. This was different—Fae territory. Nyx moved beside her, their shadowy form rippling like ink in water. "The Veil is thin here," they said, voice barely a whisper on the breeze. "We walk between worlds." The third member of their small party, Isolde, stepped forward with practiced grace, her silver hair catching what little sunlight filtered through the canopy. She moved without disturbing a single leaf, leaving no footprints on the soft moss beneath them. "My home," Isolde said, her pale lavender eyes surveying the grove with familiar affection. "Few mortals have seen it." A pause, then: "Fewer still have left." Rory wasn't sure if that was a warning or simply a statement of fact. With Isolde, it was difficult to tell. The half-Fae seer spoke in riddles, and though she couldn't lie—a compulsion of her heritage—she could certainly mislead. "It's beautiful," Aurora said, because it was. The further they ventured into the grove, the more otherworldly it became. Wildflowers bloomed in impossible profusion despite the December chill outside the grove's boundaries. Blues and purples dominated, but here and there, brilliant reds and golds punctuated the landscape. Butterfly-like creatures with wings of gossamer flitted from bloom to bloom, trailing luminescent dust. "Are we... still on Earth?" Aurora asked, reaching out to touch a flower with petals that seemed to be made of glass. It chimed softly at her touch, a delicate musical note that hung in the air. "Yes and no," Isolde replied, moving ahead of them. "The Grove exists in the spaces between. Like our shadow friend." She nodded toward Nyx. "A fold in reality where Earth and the Fae Realms overlap." Nyx drifted toward a pool of water so still and clear it looked like polished obsidian. When they leaned over it, their reflection showed not the shadowy form they currently wore but a man in 17th-century clothing—Aldric, their human form from long ago. "The waters remember," Isolde said softly. "They see beyond the Veil of time as well as realm." Aurora approached the pool cautiously. Her own reflection wavered and shifted, showing not just her present self but glimpses of... something else. Someone else. A woman with her face but adorned in crimson robes that seemed to flow like wine. "What am I seeing?" she asked, touching the crescent-shaped scar on her left wrist reflexively. "Possibilities," Isolde answered, "or perhaps memories not yet made." Nyx pulled back from the water, their violet eyes glowing more intensely. "We should continue. The solstice approaches, and the Veil thins further with each passing hour." They moved deeper into the grove, following a path that seemed to appear before them and vanish behind them. Aurora noticed that the trees were changing, becoming taller, more ancient. Their bark glittered with embedded crystals that caught the light in prismatic bursts. The canopy above had shifted too—what had seemed like ordinary daylight filtering through leaves was now revealed to be an amber sky, reminiscent of descriptions she'd heard of Dymas. "The grove is responding to our presence," Isolde explained, seeing Aurora's confusion. "It shows us what we seek... or what seeks us." The air grew warmer, heavier with the scent of ripe fruit and fermenting wine. Aurora touched the Heartstone Pendant again, and this time it pulsed with gentle warmth against her palm. "Dymas," she whispered. "I can feel it through the pendant." "The realm of Gluttony bleeds through here," Isolde confirmed. "Prince Belphegor's influence reaches far. The Fae Courts and Hel have long maintained... agreements." Aurora's hand moved to the Fae-Forged Blade secured at her hip, a gift from Isolde that she was still learning to use. Its moonsilver surface was cool even through the leather sheath. "Will we need this?" she asked. "One always needs protection when walking between worlds," Isolde replied cryptically. They came to a clearing where standing stones formed a perfect circle. Unlike the stones at the grove's entrance, these were not oak but something crystalline, embedded with what looked like frozen flames. At the center of the circle stood a table laden with a feast—fruits Aurora had never seen, wines in decanters that shifted colors like mood rings, and pastries that steamed despite there being no obvious source of heat. "Do not eat," Nyx warned sharply. "Accepting Fae hospitality without understanding the terms is dangerous." Isolde's lips curved in a smile. "Wise counsel from one who exists between states," she said. "The feast is not meant for consumption but for communion. It is how we will speak with the Emissary." "Emissary?" Aurora asked. "From where?" "From Dymas," Isolde replied, approaching the table. "You seek knowledge of the Helrealms' intentions as the solstice approaches. The Emissary can provide insight—for a price." Aurora felt uneasy. Her experiences with Hel's representatives had rarely ended well. She remembered the crimson-robed reflection in the pool and wondered if it was a warning. Nyx seemed to share her concerns. They moved closer to Aurora, their shadowy form solidifying slightly as if preparing for confrontation. "What price would this Emissary demand?" Aurora asked. "That depends on what you ask," Isolde said, arranging items on the table in some pattern that made sense only to her. "But it is always proportionate. A small secret for a small truth. A great sacrifice for a great revelation." The air in the clearing began to thicken and swirl. The amber light intensified, and the standing stones began to hum at a frequency that made Aurora's teeth ache. She felt the Heartstone Pendant growing warmer against her skin, nearly hot enough to burn. "It begins," Isolde said, stepping back from the table. "The Veil parts." The space above the feast table shimmered like heat rising from pavement in summer. Colors bent and twisted, forming a tear in reality itself. Through it, Aurora caught glimpses of sprawling vineyards, magnificent feasting halls, and kitchens where chefs worked at massive stoves. Dymas—the realm of Gluttony—revealed in fragmentary images. A figure began to coalesce from the tear. At first just a silhouette, then gradually filling with substance and color. A tall, elegant person with skin the deep red-brown of wine and eyes that glittered like amber gemstones. They wore robes that seemed to be made from liquid gold, and around their neck hung a pendant that mirrored Aurora's Heartstone, though larger and more elaborate. "Ah," the figure said, voice rich and melodious. "Visitors from the mortal fold. And the exiled seer." They nodded to Isolde. "It has been some time since you called upon Dymas." "Circumstances demand unusual alliances," Isolde replied. The Emissary's gaze fixed on Aurora, studying her with unsettling intensity. "You wear our token," they said, gesturing to the pendant. "Yet you are not contracted to our realm." Aurora's hand closed protectively around the Heartstone. "It was given to me. I don't know by whom." "Interesting," the Emissary said, smiling to reveal teeth like polished carnelian. "Nothing from Dymas is ever truly given. It is always... invested. A transaction awaiting completion." Nyx moved slightly forward, placing themselves between Aurora and the Emissary. "We seek information, not entanglements," they said, their whisper-voice somehow carrying with unexpected authority. The Emissary laughed, a sound like crystal glasses clinking in toast. "Says the shadow bound by its own failed ritual." They gestured expansively at the feast. "Everything is an entanglement, dear Shade. The question is merely what terms you find acceptable." Aurora stepped forward, one hand still on her pendant, the other resting on the hilt of her Fae blade. The juxtaposition wasn't lost on the Emissary, whose eyes narrowed at the sight of the weapon. "What can you tell us about the solstice ritual?" she asked. "Why is Hel so interested in the weakening of the Veil this year specifically?" The Emissary's smile widened, revealing more teeth than seemed possible in a human mouth. "Ah, you ask the expensive questions, little mortal. What are you prepared to offer in exchange?"
