Vices and Virtues — otherwise known as “Demon Verse” — features characters who appear as demons and angels, and whom embody any of the seven deadly sins (vices), or seven heavenly virtues. Sometimes a character can embody more than one vice or virtue, and occasionally they can embody a mix. Characters also tend to have one or two elemental affinities for their magic.

The setting takes place in a fantasy version of heaven and hell, and includes other creatures and references to demonology.
