Why Celestial Astrology?

For Players: Your character becomes part of something larger than themselves. Your zodiac sign isn't just backstory - it's mechanical identity that grows with you, resonates with the moon, and connects you to cosmic forces that have watched the world since before mortals existed.

For DMs: You get a complete toolkit for celestial-themed campaigns. Track moon phases to create tension. Build prophecies around zodiac signs. Use the organizations as allies or antagonists. Drop adventure hooks that tie directly to characters' cosmic identities.

For Everyone: This isn't bolted-on content. Every element - signs, phases, subclasses, feats, spells, items, backgrounds, organizations - works together as a cohesive system. Use it all for a campaign steeped in celestial wonder, or pick individual pieces to enhance any game.

Please note: While all text content in this book is entirely handmade, some of the illustrations were created with AI. We want to be transparent about this.
