Within Heartglade Forest.
After leaving the Spear Pillar, Aven headed straight here. From the memories of the three grand sorcerers, he already knew exactly what that ever-spreading aura of death was. As he continued walking deeper into the forest, the deathly aura grew stronger and stronger. In only a short time, the aura of death had already spread throughout the entire Heartglade Forest and was continuing to expand toward the whole of Heartglade City.
"Lilligant, Natural Reversion!"
Upon hearing Aven's words, Lilligant nodded solemnly. Through its connection with nature, it could feel the entire forest crying out as life and grass energy gradually faded away. Soon, as Natural Reversion was activated, life energy and grass gathered around Lilligant, enveloping Aven and isolating the surrounding deathly energy.
Seeing this, Aven turned to Gardevoir beside him and said, "Gardevoir, let's head to the very center of the land of death."
"Garde~ voir~"
Gardevoir nodded seriously, and with a flash of teleportation, it brought Aven and the other Pokémon to the edge of a lake.
"Lass~"
Froslass floated quietly to one side, having already sensed the dense aura of death emanating from within the lake.
"Found it!" Aven's expression turned grave as his psychic power extended outward without hesitation. As his consciousness delved deeper into the lake, countless images appeared in his mind, finally fixing upon a massive cocoon interwoven with dark red hues.
Around the giant cocoon, countless strands of death and life energy intertwined, drawing in all the life energy of the surrounding area and continuously feeding it into the cocoon. At the same time, deep within it, a heartbeat like rolling thunder could be heard again and again.
"Found it—the Cocoon of Destruction."
By the lakeside, Aven abruptly opened his eyes, his expression heavy. Within the Cocoon of Destruction lay none other than the legendary God of Destruction—Yveltal! Yveltal was a Legendary Pokémon from the Kalos Region, one that would bring disaster and destruction to the entire world whenever it appeared.
When Aven first learned that the source of death was Yveltal, even he had been shocked. He never expected the sorcerer organization, in pursuit of its goals, to bring Yveltal—still in its Cocoon of Destruction form—to Sinnoh. If he hadn't successfully captured the three grant sorcerers and repelled the sorcerer leader at the Spear Pillar, once Yveltal emerged from the Cocoon of Destruction, Sinnoh would inevitably plunge into utter chaos.
"Fortunately, it's still only in the Cocoon of Destruction form. As long as we defeat it and seal it again, this crisis can be resolved." Aven took a deep breath as several Poké Balls appeared in his hand.
Although he could rely on the power of the Creation Trio to defeat Yveltal, the spatial stability of Sinnoh was extremely fragile at the moment. He did not intend to let the Creation Trio, who were busy stabilizing space, enter battle.
"This time, let's test whether our own strength can truly shake this overgodly beast!" Taking another deep breath, Aven threw out the Poké Balls, and numerous Pokémon appeared on the field.
Lilligant, Froslass, Gardevoir, Rhyperior, Naganadel, Heatran, Darkrai—and in addition, the three Forces of Nature and the three Regis also appeared, each radiating powerful energy. After the deaths of the three sorcerers, the Forces of Nature were finally freed and naturally came under Aven's command, becoming part of his territory's combat strength.
Whether it was Landorus, Thundurus, or Tornadus, all of them were immensely beneficial to territorial development—especially Landorus, revered as the God of Harvest. Landorus could absorb wind and lightning, converting them into energy to nourish the land and make it fertile. It rarely appeared before people, only manifesting when people prayed together, bringing hope of a bountiful harvest.
With Landorus's power, the entire Sinnoh Region could instantly become a land of abundance. Combined with fertilizers and the strength of Grass-type Pokémon, no one in Sinnoh would ever go hungry again, liberating vast amounts of labor.
As for the three Regis, they had originally been discovered by the sorcerer leader within the three ruins on Mt. Coronet. Their existence greatly stabilized the Region itself. After the sorcerer leader's departure, the three Regis were naturally freed and pledged their loyalty to Aven, the King of Sinnoh, becoming his guardians.
This time, knowing that his enemy was a mythical being, Aven had brought the three Regis as well, to assist in defeating Yveltal and resolving this final crisis of the Sinnoh Region.
"Prepare yourselves, Forces of Nature—call Yveltal forth!"
At his command, the Forces of Nature trio nodded, shooting up into the sky. Thunder and violent winds instantly filled the heavens. All of that power rapidly converged onto Landorus, where wind and lightning were absorbed and transformed into dense earth energy.
BOOM!
Rumble, Rumble—!
The ground began to tremble violently, and the waters of the Lake of Death churned wildly. The sky turned pitch-black, thunder roared, and furious winds howled as deathly energy surged endlessly.
Within Heartglade City, the city lord stared intently toward Heartglade Forest, her expression solemn. "It's begun."
"REGI—!"
Regirock struck the ground with a single step, intensifying the tremors until the earth cracked and rolled apart. With three guardian deities acting together, their overwhelming power rapidly altered the world itself. Under the thunderous roar of earth energy, the Lake of Death shuddered, and its waters sank swiftly into the ground.
Before long, the lake vanished entirely, exposing the massive dark red cocoon. This was merely a greeting—a greeting to awaken Yveltal—at the cost of an entire lake disappearing in an instant. The Cocoon of Destruction resembled an enormous Pokémon egg, endlessly protected by intertwining death and life energies.
Seeing this, the Pokémon by the lakeside launched their attacks—life energy, gray mist energy, spatial energy, explosive energy, Ultra energy, magma energy, nightmare energy—all surged toward the Cocoon of Destruction!
BOOM! BOOM! BOOM!
Under the impact of such immense power, the Cocoon of Destruction trembled violently. With a cracking sound, spiderweb-like fissures spread across its surface. Stimulated by countless energies, the heartbeat within suddenly accelerated, as though something terrifying was awakening.
In an instant, the entire world seemed to dim, turning gray and pale. Oppressive deathly energy spread through the air as black mist rose skyward. A furious screech rang out, and overwhelming malice engulfed the battlefield.
Dark power spread rapidly, filling every inch of space with a special energy that made the Pokémon present tense up. Darkrai instantly moved to stand in front of Aven—it could clearly sense the Dark-type energy surging throughout the field.
"It's out—the Dark Aura!" Aven's expression was grave as the Dark Aura began to force out other energies, threatening to fill the entire space solely with Dark-type power. In response, the surrounding Pokémon activated their own energy, fiercely competing for dominance as the space itself seemed on the verge of shattering into countless fragmented realms.
Amid the violent energy clashes, the Cocoon of Destruction finally shattered completely. A massive avian Pokémon slowly opened its ghostly blue eyes, a gaze embodying the very will of death. As the Dark Aura surged, Yveltal spread its wings, the massive claws upon them and the five talons at the wide edges of its tail opening together. Black mist poured from its red skin, instantly petrifying everything around it.
