Cults of RuneQuest: The Lunar Way is the player's guide to the deities of the Red Moon. Each cult dives deep into the mysterious and misunderstood Lunar gods, and provides mechanics for each of their cults to create your RuneQuest adventurer. 15 brand new cults, including Jakaleel the Witch, the Goddess of Youth Teelo Norri, the Chaos demon known as the Crimson Bat, and the Red Goddess herself - all playable for the first time! Rules to create brand-new RuneQuest adventurers belonging to these cults, detailing the skills, passions, spirit magic, and Rune magic each cult offers. A new and unique Lunar magic system, plus expanded rules for Lunar sorcery, and the unique way Lunar Rune spells are affected by the phases of the Red Moon. Rules for how your adventurer can grow into a God-talker, Rune Priestess, or even a mighty Rune Lord. This supplement can be used with the RuneQuest core rules, or combined with other Cults of RuneQuest books to create a RuneQuest adventurer belonging to multiple cults.
