This story is a one shot that I wrote for one of my patrons on Patreon by the name of Cylestea! One of my rewards is that I will write a one-shot about whatever you want to see (within reasonable limits).

The prompt was about the character of Princess Serenity, who judges the souls of the dead to rest eternally in the Summer Lands, or burn forever in Tartarus.
