Esmerelda

The most popular Halfling deity, Esmerelda is the Goddess of Hearth and Home. Worship of Esmerelda is free of strictures and demands for worship, and her only rite of note is Pie Week, (in)famous throughout the Empire for its gluttonous excesses. During Pie Week, if at no other time of the year, Halflings can be said to be devout to the core of their being.
