The trainers followed Tracey to the Pokémon Centre. This one looked like it was made of pretty coloured stones, including the traditional giant Poké-ball on the roof. Inside, another Nurse Joy stood behind a marble desk. "May I help you?" She asked as the group walked in. Brock and Tracey both stepped forward then glanced at each other warily, as if they were about to repeat the argument they had had less than half an hour ago. Misty quickly saw the situation and pushed the two teens apart. "Don't start that again. We have more important things to do." She said in an exasperated tone. This brought the two teens back to Earth again. Ash walked up to the desk, with Pikachu on his shoulder. "My name is Ash Ketchem. Officer Jenny told me that someone left a message here for me." He told the Nurse. Joy nodded and took something out from behind the desk. "Here you go, Ash. This came a few days ago." She told him as she handed him a piece of paper. Ash thanked Nurse Joy and followed his friends so some seats nearby. He read the name at the bottom of the note as he sat down. "It's from Professor Oak." He told the others. "He wants me to call him as soon as I can." He said as he read the rest of the message. He glanced up at the computer terminals. "I guess right now then." He said and stood up.
"Hi there, Professor!" Ash said when Professor Oak answered. "Oh, Hello Ash. I suppose you got my note." He said with a serious look. Ash nodded. "Is there something wrong?" He asked lightly. "As a matter of fact, there is." The professor said, still looking very serious. This brought the others to attention. "What is it, Professor?" Misty asked from beside Ash. Professor Oak cleared his throat. "I suppose that the four of you have already visited some of the Poké-points around Crystal City." He began. The trainers all nodded simultaneously. "Then I would assume that you noticed the disappearance of many of the Pokémon at the points." He continued. The trainers nodded again. "Well, about a week ago I was asked to find the cause of this, and I discovered that the Pokémon are all travelling far out west-so far that they have gone past the Pokémon Boundaries." He finished. Ash looked confused. "What's a Pokémon boundary?" He asked. "Around the edge of these islands and the mainland, there is a boundary that no Pokémon would usually cross. Outside of this boundary, it is like another world. There are still humans, and all of the kinds of habitats that you have seen here, but the wildlife there is quite different. Instead of Pokémon, there are other kinds of creatures altogether-although some of them resemble Pokémon." Professor Oak realised he had gone off track. "Anyway, a group of people from both the orange islands and the mainland are all heading west-past the boundary-to see if they can round up the wandering Pokémon. I have sent Gary along to help." An angry look crossed Ash's face. "Gary!" He thought, then had an idea. "Maybe we could go help." Ash suggested. The professor smiled. "I was hoping you would say that." He said, then paused. "There were rumours that some new Pokémon had recently been spotted at some of the points. I currently have another Pokédex upgrade available, based on this data. If these Pokémon really exist, then you may need it on your journey." Ash smiled. "Do I just send my Pokédex to you like last time?" He asked. Professor Oak nodded. He pressed a button on his computer keyboard and a slot on the computer opened, just like last time. Ash put his Pokédex into the slot and waited the few seconds for it to come out. "When you open it, you will find another button below the others. Pressing this will bring up the images of the new Mythical Pokémon. The Pokédex will tell you about any information we have on them." Ash nodded as Brock thought of something. "How are we going to get to the place on the other side of the boundary?" He asked. "The place is called Tokyo' and I believe that until the Pokémon are back at the Poképoints, a ferry will be running to and from a bay there. I don't know much else about the roundup, the Nurse Joy of Crystal City should be able to help-she will be one of the people collecting the Pokémon that are rounded up and sending them back home." Ash smiled. "Thanks for telling us about all of this Professor. I'll call you if I get any news." He said before disconnecting the line. He then opened his Pokédex and sure enough, there was another button on it, labelled Mythology.' He pressed the button and the silhouette of a Pokémon appeared. It looked like it was made of something boiling, and had steam rising from it. "Larva." Said Dexter. "The Spitfire Pokémon. Larva is thought to be the evolution of Magmar, and to look like boiling volcanic rock. It is assumed that Magmar must need both a high power level, and a fire stone to evolve." Tracey raised his eyebrows. "Wow! I didn't know Magmar had an evolution!" He exclaimed. "What else does it say in there, Ash?" He asked. Ash pressed the button again, and this time about three silhouettes appeared that looked a lot like horses. "It has been said that there is a group of Pokémon known as the Elemental Ponies. Each one of them is a different element. One of these is the common Ponyta, and many Pokéologists agree that the others would be about the same size, weight and build. One of these semi-discovered Pokémon is known as Ponylea, the grass horse Pokémon. Also, it is said that a rock and an electric type exist, though they may only be rumours." All the trainers listened in on every word. "Wow, a whole new group of Pokémon!" Misty exclaimed. "I couldn't help over hearing." Said a feminine voice. The trainers turned to face the nurse as she continued. "If you have the Pokédex upgrade, then I suppose you four will be going on the round-up as well?" She asked. The trainers nodded. Nurse Joy pulled a sheet of paper from the pocket of her uniform and handed it to Ash. "This is the schedule that the ferry to and from Tokyo is running on. It would probably be a good idea to leave as soon as possible." She said, them walked back to her desk. Ash glanced at the timetable. "There are four ferry's going to and from Tokyo everyday." He told them. "Maybe it would be a good idea to stock up on supplies tonight, then go first thing in the morning." Brock said. The others agreed, so they set off to the Crystal City Market.
At the same time, two women with long, blonde hair walked into town. They looked around as they walked. "Excuse me, are you looking for someone?" Officer Jenny asked them. They looked alarmed, then calmed down. "No one in particular, officer." Said one of the women. "Maybe you could help us." Said the other. This one had a strange and fake sounding voice, but Jenny dismissed it. "We've just come from the woods surrounding this city, and noticed that few Pokémon seem to be around." Said the first woman. Jenny nodded. "All the Pokémon have been disappearing from the points. There are next to none left now any of them: Sapphire, Emerald, Amethyst, Ruby, Aquamarine, Diamond, Quartz, Sphene, Amber, Opal or Jet Point. A whole group of Trainers and others are going to find them." The two women nodded. "Thank you, officer." Said the fake sounding one as they walked away. "So we weren't crazy." The second woman said in a somewhat more masculine voice. "If they're making such a big deal about this, then there must have been some very rare Pokémon there." She (He?) added. "Come on, James." Said the first. "Let's get rid of these disguises and go find out what Meowth has dug up."
A little while later, Jessie and James were with Meowth on their balloon. The Scratch Cat Pokémon began to tell them what he had found out. "It turns out that all those Pokémon have gone somewhere that's past where anyone's gone before, somewhere called Tokyo" He continued to explain to them about the trip, and a little about the Mythical Pokémon that he had heard about from the Twerps' themselves.
