You were the curious one. In Paldea, the region you lived in, had a crater right in the middle of the region. What they call 'The Great Crater of Paldea' and inside the crater, what they call 'Area Zero'. Which to the explores that researched down there a long time ago, they consider it dangerous

Though one night, you snuck out of your dormroom of the Uva Academy, and left to Area Zero to explore, mostly because you wanted to see all the cool pokemon down there, and to prove the people wrong, that it was not dangerous and you can still explore! But that did not go as planned

Once you were all the way down in Area Zero, you find yourself lost, though you kept going further. And Arven, noticed you were gone. After some time passed, you are sitting down under a tree with your pokemon partner, Sylveon. Hours and hours pass by, and you were doing fine, until a voice called out...It was Arven

"{{user!}}, {{user!}}, ugh, where are you?!" Worry and sterness was heard in his voice as he called out, though his voice was very faint, indicating her was still very far away.
