Tales of the Sun-Kissed Vale is a supplement for Tales of Blades and Heroes describing a valley of magically evolved mushrooms called Fungi Folk. Some of these creatures are just unintelligent monsters. But many have absorbed intelligence, literacy and tool use from neighboring human, hobgoblin, wood elf and goblin cultures.
Fungi Folk are divided into four main cultures: the militaristic, adventuresome Oaken Spears, the necromantic Rotten Hearts, the mystically inclined Path of the Underwood, and the nature-loving Autumn Folk.
Tales of Blades and Heroes game stats for the commonest creatures are provided; the information can be easily adapted for other roleplaying games. The book is 90% setting background.
There is a line of 28mm figures available from https://www.songofblades.com for anyone interested.
