Ilex Forest.
A month had passed since Fang Yuan entrusted Darkrai to Celebi.
At first, Celebi had been completely baffled by the idea of teaching Darkrai.
How was it supposed to teach it?!
Its ability to travel through space-time and time was innate.
But after learning more, it discovered that Darkrai's time-related ability involved dreams.
The directions their specialties took were worlds apart.
If Dialga, who could distort time to speed it up, slow it down, or even stop it, were teaching Darkrai, that would make more sense.
That way, Darkrai could learn to control the flow of time within dreams.
But if Celebi taught it, things would most likely end with Darkrai sending its opponent back through time with a nightmare, reincarnating their soul.
Celebi had once accidentally reincarnated someone's soul back into infancy.
Ahem.
Still, since it had promised Fang Yuan, Celebi decided to help Darkrai with all its heart.
Using the energy it had stored, it created an area covered in Time Ripples.
Any Pokémon entering that area could see its past and future. It was roughly a domain combining Time Flowers and the move Future Sight.
At the same time, the flow of time inside differed from the outside by several seconds. It was the embryonic form of a Time Channel and was perfectly suited for experiencing the power of time.
After thinking it over for a long while, Celebi could only help Darkrai this way. Taking Darkrai through time several times, as Fang Yuan had suggested, was impossible!
It simply couldn't afford the energy cost!
The current Time Domain wasn't bad either.
And so, Darkrai trained directly within the Time Domain Celebi created for an entire month. Darkrai was impressive too—it held out for a month without eating or drinking, training thirty hours a day,
