2015 · 代替ルール（基本ルールの変種）
Between Star & Void
This supplement expands the setting of Star Knights and Void Knights, covering their ancient history, philosophies, martial styles, tools, and mysterious Meditations. It adds four classes, including the Mystic, Star Pilot, Alien Star Knight, and Way Adapt, along with more than 20 new Meditations, Star Sword variants, weapons, ships, and other gear. Optional rules introduce martial styles, combat techniques, Corruption, the path to the Void, Eclipse Knights, and a Meditation system based on permanent abilities rather than daily preparation. Conversion guidelines support use with several fantasy OSR systems, and an optional Reaction Roll system is included.
