As the child, Shira, along with her people, left the enchanted woods, Xerneas observed from a distance, hidden by the mist that enveloped him. Sensing the genuine concern and care of every creature that had gathered around him during his brief stay, Xerneas felt a profound connection with the inhabitants of the forest.

The great elks and deers, their majestic forms bowed in a gesture of reverence, silently conveyed their respect to the departing guardian. Wolves, in their pack, howled under the moonlit sky, their mournful yet respectful voices echoing through the woods. Even the birds, concealed in the darkness, screeched their melodic farewells to Xerneas.

Though he had spent only half a day among these beings, Xerneas could sense the depth of their attachment and the sincerity of their emotions. Every creature, large or small, had come together to express their care and gratitude.

With a graceful stride, Xerneas walked away from the gathering, disappearing into the mist that he had conjured to shroud his presence.

During that night, a strong mist descended upon the region surrounding Castle Darry and the adjacent river. Most men had retreated to their homes, unaware of the mystical presence weaving through the mist. Those who dared to venture outside found themselves disoriented, lost in the sudden emergence of the ethereal haze.

Xerneas, concealed within the cloak of mist and darkness, moved with a graceful elegance towards the distant Vale. The night provided the perfect cover for the legendary Pokémon, allowing it to traverse the land unnoticed. With a speed that rivaled even the most formidable Pokémon, Xerneas effortlessly covered vast distances, leaving a trail of mist in its wake.

Before the first light of dawn painted the horizon, Xerneas stood near the top of a mountain, overlooking the vast expanse of the Bite. The bay, a large inlet off the north-eastern coast of Westeros, separated the southern coast of the North from the northern coast of the Vale of Arryn. The Neck ran along the western edge of the bay, and the islands known as the Three Sisters lay within the Bite.

Though the mountains of the Vale were known for their inhospitality and challenging terrain, Xerneas, as a Pokémon, effortlessly navigated the peaks. With a graceful leap, it soared through the mountain range, the strong mist cloaking its movements.

Descending from the lofty heights of the mountain, Xerneas moved towards the Bite, its ethereal form hidden within a cloak of mist. The fish in the bay seemed to part, creating an unusual and mesmerizing path for the legendary Pokémon as it approached the waters of the Bite. Boats bobbed on the surface, their fishermen unaware of the mystical presence drawing near.

A sudden wave accompanied by the emergence of a strong mist stirred terror among the fishermen. The sea, once calm, now danced with unpredictability. Yet, amidst the chaos, the presence of Xerneas remained concealed. Xerneas bypassed the ships with an otherworldly finesse, not causing a ripple in the water.

As Xerneas crossed the vast expanse of the Bite, it moved with a purposeful elegance. The mist clung to its form, a protective shroud that masked its presence from those who sailed the bay. The Three Sisters, nestled within the waters of the Bite, bore witness to the silent passage of the guardian of life.

Leaving the bay behind, Xerneas continued its journey towards Moat Cailin, the once ancient stronghold of the First Men.
