From publisher blurb:
This is a monster compendium for the world of Hereva to play in a 5th edition RPG game. A few of this monsters need the main book Witchcraft: Magic of Hereva because they use spells found there. But you could change those spells for any other as you see fit.
The world of Hereva is a world of magic, inhabited by fantastic creatures and brave adventurers. The world itself is so magical that it doesn't have a static map, it changes so fast that people need to update their maps every once in a while. In this world, everybody is capable of manifesting magic in small ways, but there are few as proficient in magic as the Witches of Hereva.
Pepper & Carrot is a web comic created by David Revoy, about a young witch called Pepper and her mischievous orange cat Carrot. In the comic, Pepper learns about how to be a witch from her three teachers, who despite not being like teachers in other magic schools, always teach her good lessons in their own way.
In Hereva, magic reaches everywhere, all people can do at least a little magic, even animals and places have magical aspects in them.
