It would be tempting, wouldn't it?
All it would take, really, is the will. Oh, certainly every last vestige of willpower that could be summoned.
But it would be tempting.
Think of it.
The power to resurrect that which no longer exists...or create that which only exists in the mind's eye. All of it perfect in every detail.
The power to make the dead live again...
...To redress any wrong...
...To rewrite history with a happy ending.
The power to be God.
