World Tree of Beginning
Roy had never seen such an enormous tree before.
From where he stood, a third of its canopy was hidden above the clouds, its peak utterly invisible. Its trunk was as thick as a mountain, a true tree that pierced the heavens. Even the Jianmu of the Classic of Mountains and Seas or the World Tree of Norse mythology would be no more impressive than this.
World Tree...
Right, Roy remembered. In the Pokémon World, there was something extremely similar to the "World Tree."
—The World Tree of Beginning.
In essence, it was not actually a tree. Its trunk was made of rock formations shaped like a tree, while its leaves were biological tissues capable of absorbing light energy. Fundamentally, it was a crystalline life-form that relied on sunlight to replenish its energy.
The World Tree of Beginning was a conscious, living-like entity. It could be regarded as an immobile, colossal Pokémon.
And there was another Pokémon that shared a symbiotic relationship with the World Tree of Beginning.
—Mew.
The legendary Mythical Pokémon.
There was more than one Mew. It was said that in the ancient era of the Pokémon World, there had once been a tribe of Mew. However, some great upheaval occurred over the long passage of time, causing the tribe to fall apart. In the end, only a few remaining Mew wandered across the world.
And no matter which Mew it was, its abilities were extraordinarily astonishing.
Legend said that Mew had no gender.
Legend said that only those with pure hearts and a powerful desire to meet it could make Mew reveal itself.
Legend said that Mew possessed the genetic factors of all Pokémon and could learn every Pokémon's innate moves. Therefore, many believed it to be the ancestor of all Pokémon.
