Backgrounds of the New World
This 23-page supplement provides 14 character backgrounds for use during character creation. Each background includes features and characteristics that offer ideas for developing a character’s story, with most designed around Greek mythology settings such as Theros or Arkadia. The themes can also be adapted to other campaign settings. Several backgrounds draw on the guild member concept and expand the available spell lists for spellcasting classes.
