Granted, but ONLY you live in the castle. And it has no modern plumbing or electricity or internet access or maintenance, so both you and your castle are left to slowly decay to boredom and time. Of course you still have the castle... Though you have no money to support it and since you're implicitly doomed to live in the world of Fable the only job available are repetitious and mundane. And there are only three of them, I hope you like repeatedly pouring and tossing mugs of ale off of a counter. And this isn't even including the plot holes that rip and tear at reality around you, which is constrained by alien and maddening geometries that limit your movement to the paths in the game... After all, nothing else exists but scenery.
...Since my wish was only DENIED, and not properly corrupted.
I wish to destroy everything and create a monument to non-existence!
in trade it shall be corrupted and you will recreate/create everything that has been destroyed or yet to come,you get mutated by accident and look worse than a pufferfish,and you got caught by the english and condemned as a demon but as you were resistant to fire,you got locked up by chains that could not be broken and offended a witch in the same cell as you were and was infected by a fusion of curses and swine flu,soon all the soldiers deserted as they feared of swine flu and you was left alone for millions of centuries suffering from breathing disability,sneezing,infected liver,rhumetism,smelly farting,hunger,necritic paw,infected rigth eye and so on. when explorer foo foo found you in an ancient cell(after centuries),all he brought back was sand that used to be your bones(sorry if I offended you,its just my iagination)
I wish that py wish is to start all corruption and make it never ending
Granted, but this bizarre alteration to existence has removed any trace of you as you were never born. And since, by effect, YOU don't exist from this wish, then the wish could never be made. Congratulations, you've created a paradox of non-existence and absolutely nothing has happened.
