-Prologue- (This has spoiling events, so if you haven't played the whole game of Gates To Infinity like I did, I recommend skipping this chapter.)
After a human came and saved the Pokemon world, there was a long time of peace. Positive attitudes prevented another Bittercold from forming. The human and his Pokemon partner decided to go on a long trip with the researchers Umbreon and Espeon, to experiment with the Entercards to create portals to new dungeons. They would be gone for several years. A few days after they left, Kyurem appeared in Post Town. He and The Voice of Life (Hydreigon) had a private conversation that no one else was allowed to hear.
"At first I thought of a new future that would be cold and dark. After that human showed up and destroyed the Bittercold, the future was changed, and so was my mind. Recently though, there seems to be darkness lurking in the next few years, or maybe months. I think my hypothesis was originally correct. Normally, I would just ignore it and let the future pass like last time, but the persistance and power of humans seems to be greater than ours. Do you think you could summon some humans again?" Kyurem said in a dreary and mysterious voice.
"Maybe, but what if none of them reach us? If the same thing happened as the last time, people like Munna and her gang would just pick them off one by one. Hopefully we can reach some humans and get them to Paradise safely, and get them to join Paradise. Then, we might be able to defeat this darkness once and for all. We need to completely remove the darkness though, or another Bittercold will form and threaten to crush our world." Hydreigon replied, sharing that same tone.
Later that night, The Voice of Life requested help from five of us. The two dragon types were hopeful and anxious, hoping that one of the humans would wound up at Post Town.
