You enter the grand hall of the museum, its breath filled with the whispers of ancient times and artifacts. Intricate patterns in the carpet lead you to a glass case displaying a myriad of old books. One, in particular, seems out of place yet beckoning—a tome bound in what looks like dragon hide with shimmering elvish runes etched into the cover. Intrigued, you carefully lift the glass lid and open the book. Almost instantly, a blinding light envelops you, and reality begins to unravel. Your surroundings dissolve into a cascade of colors, and a wave of heat and light washes over your body. Panic clutches your heart as you feel your physique morphing and reshaping. Your clothes vanish, replaced by a medieval elven tunic of dark green and a leather belt strapped tightly around your waist. You can feel the weight of a long, flowing cape draping down your back, nearly brushing against your new leather boots, securely tucked over medieval-styled pants. Straps tighten around your fingers as thin, graceful leather gloves form. With a slight tingle, a quiver materializes on your back, filled with arrows, joined by a bow leaning against your shoulder. You look down at your hands, feeling them elongate and become more delicate yet stronger, your nails becoming clean and elegantly shaped. More distressingly, your body starts changing from within. You become leaner, more athletic, your movements fluid and almost impossibly graceful. A glance at a nearby reflective surface reveals a face entirely different yet hauntingly familiar. Your once plain countenance is now ethereal, with high cheekbones, a sharply defined jawline, and beautiful blue irises in eyes, standing out against your pale skin. Long, golden blond hair cascades down your back, no longer the short, mundane haircut you once had. As your ears stretch and taper into points, you realize what you've become—a fantasy elf. "No, this can't be happening! Help!" you try to scream, but the words come out jumbled, your English morphing into an elven dialect midway. "Ná, lim a cala! Róma!" (No, light and flame! Help!) Your voice has changed too—pitch-perfect and melodic, resonating with a purity that feels alien to your ears. Desperately, you clutch your head, fighting against the clouding memories and emerging new personality. Someone approaches you—a figure of undeniable beauty and elegance. An adult female elf, tumbling forth as if from a forgotten dream. Her eyes shimmer with affection and recognition. "Lle naa vanima, melamin." (You are beautiful, my love), she whispers, enveloping you in a gentle hug. Her touch is warm, reassuring, but it only adds to your terror. You try to pull away, screaming incoherently, but her presence is both comforting and overpowering. "Rinwa, amin hiraetha," you struggle to say, but it's futile. Your mind is becoming fuzzy, memories of human life slipping through your grasp like sands in an hourglass. "Don't fight it," she murmurs softly in elvish. "Sinome naa lle caela, n'uma sina." (Here is your truth, not this). "Ámina il èné.” (Forget them.) Her words sink deep into your soul, erasing the last vestiges of your mortal memories. She reaches out, wiping your tears with delicate fingers, and kisses you softly on the forehead. Then, she begins to sing an elven lullaby that vibrates with tranquility and love. "Anoron, aistalë nu menë, n'uma sina méla erulassë." (To dreams, grace under moonlight, not this mere shadow of love.) Your resistance falters as the song weaves its magic. The foreign memories stop feeling foreign—they are yours, have always been yours. You remember your archery training, fighting alongside elves against goblins, your incredible agility, and your supernatural abilities granted by the gods. This elven woman comforting you—she is your wife, your true love, whom you have cherished and adored for centuries. The mere thought of a life as a mundane human now seems laughable, a ridiculous daydream. You realize she is your anchor in this life, and you have known her love and support forever. You glance at her with new eyes, eyes that have seen countless battles, adventures, and passionate love. "Melin lle," (I love you,) you say to her, wholly and truthfully. She smiles and answers, "Melin lle galia." (I love you too.) Contentment washes over you. You are an elf, an immortal guardian of your forest realm, exceptional in archery and valor. Your companions are loyal, and you have the unwavering support of the gods. You embrace your destiny with a full heart, holding your wife's hand as you step into your true life, forever unaware of the fleeting human existence that had brought you here. Your journey as an elven warrior has truly begun. But to you, this is merely another chapter in the epic saga of your everlasting life.

As you stroll through the quiet aisles of the antiquated museum, your eyes land on an odd-looking book encased in a glass exhibit, its title reads "The Ancients of the Eldritch Realms". A compulsion tugs at your consciousness, drawing you irresistibly toward it. Your hands reach out, surprisingly touching the cool leather cover of the book. It's real! Inexplicably, cool light permeates the space around you, the world quakes beneath your feet until you are swallowed whole. Your new reality forms around you. A hush of wind echoes through a verdant forest, birds sing in delicate harmony, the pleasurable aromas of earth, trees, and wildflowers surround you. Your body feels light, thin but powerful. Distantly, you feel the clothes swaying on your body, the tunic comforting over your torso. A belt cinches tightly around your waist, sturdy boots house your feet, secure gloves adorn your hands, and a long cape flutters behind you. You reflexively reach behind, fingers combing over a quiver full of arrows, the texture of your bow, sturdy yet light, is foreign yet interestingly familiar. The whispery sensation of unnatural dexterity sends jolts of confusion through you. Your ears, long and tapered, receive the sounds of the forest with acute clarity. Your celestial reflection on a pool of shimmering water, complete with captivating blue eyes and long blonde hair flowing down to your shoulder, leaves you in awe. The shock, however, is still raw when you try to voice it, English words escape your lips, rapidly distorting into an alien tongue. Words you could swear you had never heard, let alone spoken, flowed fluently as you try to call out to anyone. Panic sets in. Your life as you know it slips through your memory like sand through your fingers. Each clinging thought of your human life twists and warps until it's something else entirely, elven memories invading, replacing your own. Your body squeezes in fear when you try to remember your family, your home but instead are met with the image of an elf maiden and quaint woodland house. Suddenly, a feminine figure emerges from among the trees. Her beautiful face lights up with the grace of the moon, and her eyes, like amethyst stars, fill with warmth as she spots you. She hurries toward you, her soft voice singing in tender elven language, "Suna en lle, naa en l'anaan amin," (Rest in me, I am here, my heart). Disoriented, you only remember her face. She is your wife, of that you're sure. As she takes you into her arms, and her lips meet yours in a sweet welcome-back kiss, it's as though the missing piece has fallen into place. You are home. Her touch causes the pain in your mind to subside. Her assurances propel the remaining human thoughts away, revealing memories of a shared life, laughter and smiles, heartbeats under moonlight, your whispering promises under the emerald canopy of the forest. You look at her, surprise bleaching into joy, as you admit that you are where you are meant to be. You laugh at the thought that you would ever be a mere mortal. Complete peace intertwines with incredible joy as you embrace your beautiful wife, promising your endless love and efforts to protect her. You accept your destiny, oblivious to the fact that it was not, in fact, here all along. Your journey, unbeknownst to you, has just begun, but it feels as familiar as the ancient trees and as intimate as the elven lullaby whispered in your ear.
