Logo for Hidden Worlds: Refined Core, a game with a fantasy or adventure theme, featuring rugged and weathered text style in yellow and black.

Vampires. Fairies. Dragons. Welcome to the Hidden Worlds.

There is an entire world hidden from the consciousness of humanity. The myths and legends that haunt our histories and traditions are real. In the Hidden Worlds Refined Core, each character has experienced an incursion event in their life. This has opened their eyes to the hidden worlds, and they will have to determine how they respond.

From unique character creation to immersive storytelling, this game encourages the player to delve deep into their character’s history as it shapes their character’s life in this new hidden world before them. The players will explore the dark, hidden world of mythological monsters, dark cults, and other paranormal creatures.

The combat system is quick and deadly, where the players use only a single d20. The gamemaster has fluid control over encounters and challenges, and the target numbers are quickly, and easily generated during the story. With no character classes and no levels, the players have control over their characters, and there are virtually no limits for the players, or characters.

The Refined Core version of the game is the new core standard ruleset. All of the future releases will use the Refined Core as their basic ruleset.

NO CLASSES. NO LEVELS. NO LIMITS.
