In the days that ensued, Eldranthor, the sojourner from a realm beyond, embraced the wisdom proffered by the library, under the aegis of the sagacious Elara and the steadfast support of his newfound confidant, Fenryr. The more Eldranthor consorted with Fenryr, the more he realized that his comrade-in-arms had never cast doubt upon his celestial origins, embracing his otherworldly provenance without qualm or question.

  Upon a morn, as they broke bread together in Fenryr's snug abode above the scriptorium, Eldranthor's inquisitiveness finally took hold of him.

  "Fenryr," he began tentatively, "I have observed that you have accepted my existence hailing from another realm without hesitation or suspicion. Not once have you sought explanation or evidence. Pray, tell me the reason for this."

  Fenryr regarded him pensively for a moment, his eyes faraway, as though contemplating the ramifications of divulging a long-concealed enigma. At length, he heaved a slow exhalation and spoke.

  "Eldranthor, there exists a reason for my unshakable faith in your tale. It is because I, too, am a stranger to this world."

  Eldranthor's eyes widened in astonishment, and he leaned forward, his curiosity piqued.

  Fenryr proceeded, "I was not merely christened after the legendary wolf of Ragnarok – I am Fenrir, the very beast itself. In my realm, I was exiled to Midgard, the domain you now inhabit, and bereft of much of my might. I have since dwelled here, in mortal guise."

  Eldranthor was dumbstruck, torn between incredulity and awe. "How came you to assume this form? And why do you not endeavor to return to your own realm?"

  The tale has been taken without authorization; if you see it on Amazon, report the incident.

  Fenryr's countenance darkened, his words laden with melancholy. "My exile was a consequence of my deeds and the terror my power wrought upon the gods. Here, in this guise, I have been granted an opportunity to ruminate on my past and unearth a new raison d'être. I have found a passion for erudition and a tranquility that eluded me in my true form. As for my return, I have long since forsaken such aspirations. My destiny is intertwined with the apocalypse, and I have made my peace with that."

  Eldranthor was touched by Fenryr's account, recognizing in him a kindred spirit grappling with loss and the yearning to discern their place in the cosmos. In Fenryr, he perceived a fellow wayfarer on the road to self-enlightenment, and their bond grew ever stronger.

  With their shared clandestine now unveiled, Eldranthor and Fenryr forged a deeper bond of trust and camaraderie. This connection prompted Fenryr to divulge his knowledge of an individual who could aid Eldranthor in procuring identification – an artisan skilled in crafting false documents convincing enough to secure a genuine credential.

  Eldranthor initially harbored misgivings, for subterfuge was not a practice he embraced lightly. Nonetheless, he understood that to wholly immerse himself in this world's knowledge and secure his place among its denizens, he needed a bona fide identity. Thus, he assented to Fenryr's proposal.

  Fenryr reached out to his associate, an unassuming but masterful counterfeiter who went by the name Lark. Lark agreed to meet with them in an inconspicuous, serene coffee house to deliberate the particulars of their request. As they reclined in an isolated corner, Lark hearkened to Eldranthor's chronicle with rapt attention, nodding from time to time and posing incisive inquiries.

  Once they had reviewed all the requisite data, Lark vowed that he could fabricate the necessary papers, albeit it would demand time and resources to guarantee their veracity. Eldranthor and Fenryr acquiesced to the conditions, and Lark commenced his craft.

  After several days of nerve-wracking anticipation, they were bestowed a parcel containing the meticulously wrought documents. Armed with these, Eldranthor succeeded in acquiring an authentic identification, and with time, he managed to weave additional layers of identity, ultimately earning recognition as a full-fledged citizen of Earth.

  Now endowed with a legitimate persona, Eldranthor experienced a sense of belonging and stability that had eluded him since his arrival. With Fenryr as his unwavering ally, he was primed to plumb the depths of this world's vast trove of wisdom, all the while pursuing a means to reclaim his magical prowess and reconcile his previous existence with his newfound life on Earth.
