Nice Prologue. Can't wait to read more. The only thing I saw wrong was the following sentence:
"His oldest son, Wasif, used to be a pokemon trainer, but he quitted after winning in the Hoenn League."
Quitted shouldn't have been used there. You should have just said "quit". Also, Pokemon should be capitilized, but now I'm being picky.
Great job though. I'm looking forward to seeing what comes next. I hope this isn't just a story that is the same plot as the one in the Ruby/Sapphire games. Trainer trains Pokemon, beats gym leaders, becomse master.
Again, great Prologue.
