Years ago, hundreds of monstrous creatures called Yokai were scattered across the multiverse we know as the Mosaic when their corrupt goddess, Izanami, was defeated. To counter these terrible foes and keep them from destroying Existence as we know it, the Shadow Scar Agency was formed. This organization of ninjutsu trained secret agents traverse the Mosaic to hunt down the Yokai before they can cause chaos. Now you can take part in this war, through Shadow Scar: Tales of the Veil War, the core rulebook for Shadow Scar!
