Spirits have always liked Nista, if she were a flame, they would be her moths. On a world where the dead never stay dead, children play with docile spirits and adults use them as domestic staff. Nista loves most, but when larger demons seek her out to feast on her spiritual light, she has no choice but to use a power she doesn't understand to crush them.
