Hmm.
It is an ending, but not a crescendo and denouement. The victims of the dice were handled almost as an afterthought, and none of the surviving wives gave Harry the furious verbal abuse he deserved for eating an AK, even if he did get better. Lavender and the Elysian fields was cool, but why would she wait and Ron move forward? I half expected Harry to bump into a distraught Ron wandering around complaining "this place rots, Harry. I can't smell anything to eat!"
Not that I believe Harry and his burgeoning clan need to care, but with all the sane mages leaving Britain, I would nearly guarantee that they have at most 20 years before the British once more threaten the magical world with a Dark Brigade of one sort or another.
In the end, I feel as though the conclusion was rushed. (Or maybe this is just my underhanded way of luring you into writing a sequel)
I had fun with the dice roll, even if the dice result gave you the least juicy writing opportunity. I will look forward to your next great adventure ... story! I meant story!
