Disclaimer: I own nothing but San and the plot.
San's POV:
I ran over to Latias and knelt beside her, " what happened?" I asked her. Celebi, Mew and Manaphy came over to listen. The others stayed back to give her space, " pokemon hunters attacked us almost as soon as we left the hall of origens. They were searching for legendaries to give to their boss... they got Latios. He protected me so I could get away." I stepped back so Celebi could start healing Latias. I walked over to an exit and looked down, hoping I would be able to see something... I did. I saw a helicopter briefly before it disappeared behind some clouds. Desperation to save my best friend's brother overtook any sort of common sense. I took a few steps back then ran and jumped, freefalling towards the ground. I heard my name called several times as all the legendaries that could fly or float jumped down after me. I came to a hard stop as Arceus himself appeared underneath me. I landed on his back just in front of the huge yellow wheel thing. I looked in slight amazement as my legs didn't even reach to each side of his back, " please Arceus! we have to save Latios!" I called to him. " I agree, but killing yourself isn't going to help." he replied sarcasticly. I made my way over to the side of his back and looked down. I then realised I couldn't even see the ground below the clouds. My eyes widened and I looked at Arceus. " you saved my life." " I'm glad you noticed." he replied in a sarcastic, joking tone. I looked up and saw Dialga, Palkia, Giratina, Darkrai, Rayquaza and the flying birds hovering above. They all went back to the hall of origens. Once the other legendaries, especially my parents expressed their relief at me being alive; Arceus stood in front of all the legendaries, telling them his plan to save Latios. I was still on his back, seeing no way to get down without him putting me down. " We can't send too many of our own in case they get captured also. If it happened to Latios it can happen to others. I am going to send Rayquaza, Kyogre, Groudon, Mew, Celebi, Ho-oh and the three beasts." he said. " what?" I shouted, echoed by my parents. " but what of San?" Raikou asked. " I will assign someone to look after the girl. It should only be for a few days. I need your skills for this." Arceus replied to them. The beasts argued, but Arceus was insisting they go. I stood with Latias, watching them standing by the entrance, ready to go. I looked back at Arceus, " I want to go with them!" I hissed. He looked at me in surprise, " nonsense child. You're seven years old, you would only slow them down." He said, not unkindly. Latias put her 'hand' on my shoulder. I knew she was also wishing to go. I sighed and said goodbye to my parents, then turned away as they left with the others. I looked at the remaining legendaries, silently wondering which one Arceus was handing me over to. I hoped it was either Latias or Lugia. I looked over at Arceus, but he didn't seem to be going to say anything. I didn't want to seem insistant so I just waited silently. " San." I turned to Latias when she spoke. " let's go fo a fly. I want to go outside for a while. Don't worry, someone will send for us when Arceus makes a descision." she added when she saw my expression. " that's not it, what if those humans come back?" I asked, " oh. Don't worry. We won't be going outside the hall of origen's safety. Promise." She replied. I sighed and nodded. I got on her back and she flew outside. We both stayed silent, simply enjoying the wind and sunshine. " San?" Latias turned round and we saw Articuno. I nodded to him and tapped Latias's neck. She followed him in then landed so I could get off her back. Arceus beckoned to me. I ran over to him, " I was starting to think you'd forgotten." I said with a nervous smile. " San." " yes?" I replied when he spoke. " do you know how to fight?" His question surprised me. " not really. My parents never taught me." I admitted. He nodded then said, " I didn't think so... San, I want you to learn. that's why I'm assigning Giratina to be your mentor in the reverse world. I believe it's important you learn to fight to protect both yourself and those you love." I narrowed my eyes in confusion, " but a few days isn't enough to learn to fight." I pointed out, " I know." He replied, but didn't continue. " what about Roselia and Ditto? my partners?" I asked. " you can bring them if you so wish. It would be wise to train your partners as you train." Arceus replied. I still didn't understand why it was nessessary for me to learn to fight, but I didn't question him. " does Giratina know?" I asked. " of course he does. I spoke to him before telling you." Arceus replied. I sighed and looked around for the huge legendary. I found him in a playful scuffle with Dialga with Palkia watching. I stayed back, staring up at the gigantic pokemon. After a few minutes of them not noticing me I left and searched for Lugia instead. When I found him I told him what Arceus said. " well, good luck to you San. It's a pity a child so young must become a fighter." he said and I hugged him. Latias flew round the corner in a great hurry, " San! is it true? Is Giratina taking you to the reverse world?" She demanded. I winced, " yeah. It's true." I replied, then asked, " who did you hear that from?" " ... Shaymin." Latias replied. We both looked out at the setting sun. " it's time to leave." Lugia muttered. I hugged my best friends and blinked away the tears that were threatening to overflow. After a few moments we stepped apart.
I stood with Giratina, Dialga, Palkia and Arceus, watching all the other legendaries gradually leave. Eventually it was just us. Giratina helped me onto the flat section of his head where I sat, looking out at the last of the sun rays. I looked over at Arceus,
" Arceus. My partners?" I asked. He nodded and teleported Roselia and Ditto onto Giratina's head beside me. They were extremily confused, but relaxed when I promised them an explanation. The four gigantic legendaries flew away from the hall of origens then vanished into their own dimensions. I looked around at the reverse world. I had a gut feeling this would be my new home for more than just a few days.
