Gennai chuckled at David's excitement.
"The eye is a wonderful mechanism," he agreed. "Its resolution far exceeds the most advanced camera or display."
He was slightly startled by Pearce's exclamation, but paid it no mind. They were all a bit out-of-sorts from this experience, no doubt, so getting it out of their systems was best.
Finally, he turned to answer Celia's question.
"Believe me, this is no dream," he said. "What you are looking at is a physical construct stored in a digital format. You might think of it like the transporter buffers on Star Trek; that's how the Programmer explained it to me, at any rate."
He paused to let that sink in before continuing.
"As to why you are here, I'm afraid the circumstances are anything but awesome." He eyed David as he said this. "This world's existence as a real place was never meant to be discovered. Unfortunately, one of your world's military organizations was able to crack the secret, and what they found is that a fully-grown Digimon is potentially far more powerful than any known Pokémon of your world.
"Desiring them as programmable weapons, they have dispatched an operative calling himself 'sonicstar229' into the Digital World, where he has begun infecting Digimon with a powerful virus that turns them completely loyal to him, not unlike a Black Gear or a Dark Ring. The difference is that the virus is not an external attachment that can be destroyed while sparing the Digimon; at this time, the only known way to expel such foreign code is to deresolve the Digimon, sending its data back here to Primary Village to be reborn.
"The Programmer did her best to combat this threat on her own, and for a short time, it seemed that she was gaining the upper hand. But, a few weeks ago, she mysteriously vanished, and sonicstar229 was able to continue virtually unopposed, if you'll excuse the pun. The Digital World itself must have sensed that the Programmer's life was in danger, and using a complex algorithm even I still don't fully understand, it selected a small group of Pokémon trainers to take her place in this fight and, even now, continues to search for more.
"The Digital World chose you because it believes you have what it takes to save it. Your mission, should you choose to accept it: Defeat sonicstar229, and eliminate the influence of his virus. If you are to succeed, I believe you must master the monsters of both worlds, Pokémon and Digimon alike."
He looked around at the assembled group.
"So, I ask you: will you accept the mantle and responsibilities of DigiDestined?"
