"I wish" Jon said as he sat on his bed holding the stone "I knew what the exact range of the stone is"
Earlier
Jon reread and reread the end of the note
**Changes made will be as if it has always been so, apart from for those within earshot of the wish or out of the range of influence of the stone. This range I estimate at several miles, but I fear I have not been able to determine an exact figure.
I must go now. Use the gift I have given you wisely, and think of me often.
Your friend, always,
Grandpa.**
"Why, why is it an estimate? Grandpa was always so praises, estimate is not the sort of thing grandpa Greg would be satisfied with" Jon said to no one. He grabbed the stone.
Present
Jon expected something more exiting like a booming voice or even a note to appear but nothing.
Jon opened his mouth to yawn but instead "The stones abilities are dependent on the spirit of the wilder. So rang reversibility and a number of other qualities are dependent on your own spirit" Jon said uncontrollably.
So if Jon was riled up or passionate he could reverse wishes, or they could affect the whole world.
