As Leo progressed, the "XB4d1CIA" part of the filename started to make sense. It wasn't just a random code; it was a seed. The game began to rewrite itself. Cities moved. New paths opened up into the "Void," a pitch-black area where his Pokémon’s cries sounded like actual whispers.
The world of Hoenn was beautiful but... wrong. Every NPC he talked to seemed aware that they were in a loop. A Youngster on Route 101 didn't want to battle; he just stood there and said, "I’ve lost this fight 4,000 times today. Can we just watch the sunset?"
