The partial failure of their intricate plan for Annabeth caused little distress; it was, after all, a mere diversion for Luke Timothy John. As two centuries of tutelage drew to a close in the year 694 of the 12th cycle, Luke Timothy John bestowed upon Jonathan and Annabeth the complete and perfected knowledge of a unique spell known as The Divide of One.
This spell was the very mechanism the being once known as Luke Timothy John had employed upon himself, fracturing his essence into the three distinct personalities now known as Luke, Timothy, and John. The original Luke, burdened with numerous universe-spanning missions, faced an insurmountable challenge: he could not be omnipresent. His tasks demanded meticulous, long-term strategizing and delicate execution, leaving no room for haste. Furthermore, the Dragon God had, immediately upon its inception, rendered cloning magic utterly non-existent. Thus, Luke was forced to utilize The Divide of One, sacrificing his core personality to manifest these new iterations of himself. Each of the three, though individually diminished in power, was now perfectly equipped to fulfill their original, overarching mission according to their unique strengths. Yet, before their separate journeys could truly begin, a message resonated through them all from The Voice of The Universe. This cosmic decree not only granted them a new purpose but also reassigned their previous missions to other entities, compelling them to fuse back into a single physical form. The universe, however, commanded them to persist as three composite entities within that unified body.
Over the years, Jonathan and Annabeth had been taught only the subservient versions of The Divide of One spell. Yet, through their profound mastery of these lesser forms, they gained the unique ability to unleash the original spell's true might, bypassing the inherent limitations that came with the subservient versions. However, there was a critical catch: if the newly created personalities, once separated, did not wish to become one again, the original personality would be lost forever.
Even if they did fuse back together, there were still significant side effects. The best possible outcome, which was less an "effect" and more a perfect restoration, was the return of the original personality. This rare occurrence happened only if the new personalities fused back within a very short period after their initial separation. The second possible effect was a slight, subtle alteration of the original personality. The third, a more drastic consequence, was the complete destruction of the original personality, with one of the dominant new personalities becoming the new original. The fourth and final effect is the creation of an entirely new personality. Furthermore, if one ever learned the complete The Divide of One spell, they would permanently lose the ability to use its subservient versions, effectively making them masters of the original but unable to step back down to the lesser forms.
In the year 296 of the 12th cycle, just two years after they had first been taught the spell, Jonathan and Annabeth could confidently wield The Divide of One. Jonathan, upon splitting, manifested two new personalities: Jon John McKellen and Nath John McKellen. Annabeth's division resulted in Anna Ruth McKellen and Beth Ruth McKellen. Each of these newly formed personalities, distinct and self-aware, chose their own names. Jon and Nath often fused back together regularly, a seamless transition. Anna and Beth, however, did so less frequently, and whenever they did, the composite Annabeth became noticeably more influenced by Anna than by Beth.
Indeed, even though Luke's (their) plan for Annabeth had not fully succeeded in pushing her entirely to the negative aspect, the split itself didn't just create two new personalities; it also inherently placed them on two differing aspects of the Silvery-White lineage. Beth embodied the positive aspect, while Anna represented the negative. The personality of Anna was considerably stronger-willed than Beth.
Throughout the two centuries of Luke Timothy John's tutelage, Annabeth had completely fallen head over heels for him. One might attribute this to Luke's subtle influence on Annabeth's personality, but even during the final two years of Luke's stay in the Velmunth Kingdom, both Anna and Beth, as separate entities, also developed profound affections for him.
