Witch of salvation. Her nature is mercy. She absorbs any life on the planet into her newly created heaven--her barrier. The only way to defeat this witch is to make the world free of misfortune. If there's no grief in this world, she will believe this world is already a heaven.
The Minion of the Witch of Salvation. Their task is measurement. They can expose the impurities of the hearts of those who go to Heaven by weighing the sins place on their scales. The sinful are perhaps granted even more profound mercy than from the witch.
