A hero does not get old they die everyone knows that .Even if they have a girl or a son or a daughter they die once their duty is finished .Just like they knew they would at the beginning of the story .Thats how it always was and always will be .
A hero does not grow old that is the truth everyone knows .They die and are laid to rest in the holy ground or are left to rot on the battle ground .
So it was no surprise that when the last battle was over Harry Potter vanished from Europe taking his godson Teddy and teddy's grandmother with him .There was a huge search for him but he was never found .Though very month he would send a letter . Each had the warning :Traveler Be Ye Warned. Here Be Monsters
Each person to look for them would disappear so eventually they stopped looking
Many years later a letter came from Teddy this time saying to go to China and that harry had finally died
One one of the mountains surrounding the Yellow river they found Teddy next to a gravestone and a small house
The only thing the gravestone said was :Harry potter ,heros don't grow old
