A Free Game of Thrones Inspired Mythology Book for Open Dungeons RPG
If you love Game of Thrones, A Song of Ice and Fire, and House of the Dragon, and you have ever felt the older, stranger mythology humming underneath all three, this free RPG book was built for you.
Deities & Demigods: The Westeros Mythos is a free downloadable mythology supplement for Open Dungeons RPG. It carries the divine powers, legendary dragons, ancient gods, cursed kings, resurrected heroes, and mythic figures of Westeros to the tabletop, written and statted and ready to play.
It is not a list of monsters with hit points. It treats Westeros as a living mythological landscape, a place where gods, dragons, bloodlines, oaths, prophecies, betrayals, and remembered deeds all gather weight until they bend the world around them. Here the divine is rarely distant. Sometimes it arrives as fire. Sometimes it watches through the trees. Sometimes it rises from the dead. Sometimes it passes overhead on black wings.
What Is The Westeros Mythos?
The Westeros Mythos is an unofficial, fan-made RPG sourcebook that explores the divine and mythic powers of Westeros through the rules and cosmology of Open Dungeons RPG. Inside you will find major gods, lesser gods, demigods, dragons, ascended mortals, divine servants, and legendary figures drawn from the mythology of Game of Thrones and the wider world of A Song of Ice and Fire.
The cast runs from the Lord of Light and his nameless opposite the Great Other to the Many-Faced God, the Drowned God, the Seven Who Are One, and the Old Gods of the North. It gathers the great wyrms, from Balerion the Black Dread to Vhagar and Drogon, and it makes room for the mortals whose stories grew too large to stay mortal: the Night's King, the Last Hero, the White Wolf, the Unburnt, the Kingslayer, the Hound, the Mountain, and many more besides.
Every entry is written to help a Dungeon Narrator bring these figures to life at the table. The aim is not only to describe what a being can do in a fight, but to capture what it feels like when it walks into the world.
More Than a Stat Block
The best part of Game of Thrones was never just the battles. It was the weight behind them.
A sword was never only a sword. A crown was never only a crown. A dragon was never only a monster. The Wall was not just ice, the Iron Throne was not just a chair, and the old gods were never just background religion. The Lord of Light was not simple fire magic, and the Great Other was not simple darkness. That weight is the whole approach behind this book.
To carry it, each entry pairs the poetry with the mechanics. You get a mythic description and full avatar statistics, attacks and defenses, divine actions, a mythic influence that reshapes the scene, a presence aura, regional effects, and the mythology that explains why any of it should frighten you. The result is a Game of Thrones RPG experience that feels heavy, atmospheric, dangerous, and legendary.
A god should not feel like a bigger ogre. A dragon should not feel like a flying lizard with extra damage. An ascended mortal should not feel like an ordinary character holding a better sword. These figures are supposed to change the air around them, and that is exactly what this book tries to capture.
Gods, Dragons, and Ascended Mortals
One of the central ideas of The Westeros Mythos is that Westeros does not reserve divine weight for gods alone. In this world certain mortals become larger than life. Their deeds harden into myth, their names become symbols, and their choices echo down through history until memory itself starts to act like power.
This book turns that idea into something you can play. Jon Snow, the White Wolf, is not handled as merely a warrior; he is a mythic survivor, a resurrected commander, a figure standing in the narrow space between the living and the dead. Daenerys Targaryen, the Unburnt, is not merely a queen with dragons; she is fire and blood, liberation and conquest, prophecy and tragedy braided into one body. Jaime Lannister, the Kingslayer, is not only a knight; he is oathbreaking and honor and shame and the slow possibility of redemption, all carried at once.
That is what separates this from an ordinary Game of Thrones stat block collection. It keeps asking a single dangerous question: what happens when memory becomes power?
Built for Open Dungeons RPG
This supplement is written for Open Dungeons RPG, a fantasy roleplaying game built around fast play, Dungeon Narrator rulings, meaningful consequences, and mythic adventure. It speaks the system's native language, leaning on Major Gods, Lesser Gods, Demigods, and Ascended Mortals, on Divine Gravity and Avatars, on Presence Auras, Regional Effects, Range Bands, and Mythic Influence, so that every figure lands as a piece of story and atmosphere rather than just another combat encounter.
Often the most memorable scenes are not the ones you win. A party may never "fight" the Old Gods in the ordinary sense. They may bargain beneath a weirwood, swear an oath there, break that oath, and learn far too late that the trees were watching. A party may never defeat the Great Other with ordinary steel. They may only survive his attention, hold out against the Long Night, or stumble onto the single impossible condition under which hope still means anything. That is where this book shines.
A Book About Mythic Atmosphere
If you are looking for a Game of Thrones RPG download, this one earns its place when you want the darker end of fantasy: divine horror and dragon-centered campaigns, White Walker mythology and the long cold pressing south. It gives you the mythic figures of House Stark, House Targaryen, House Lannister, and House Greyjoy, a Westeros-flavored divine hierarchy, gods that feel genuinely strange and dangerous, and legendary NPCs who arrive with table-ready mechanics already attached. Underneath it all run campaign hooks built from prophecy, death, fire, winter, and blood.
It also travels well beyond a strict Game of Thrones campaign. Any Dungeon Narrator can borrow the architecture and reskin it: old gods rooted in trees, fire gods who speak in prophecy, drowned gods worshipped by sea-raiders, dragon gods, death cults, resurrected champions, and ascended mortals whose legends have simply grown too heavy for ordinary history to hold.
Why You Should Download It
Download Deities & Demigods: The Westeros Mythos if you want a free RPG book that treats Game of Thrones mythology with weight, darkness, and table-ready imagination. It is written for the kind of reader who keeps wondering what R'hllor actually feels like when he manifests, what happens on the night the Old Gods are not silent, how the Night's King should bend a battlefield, what it truly means for a dragon to become divine, whether a mortal can become myth through memory alone, and what a real Game of Thrones divine encounter looks like once it is sitting across the table from your players. This book answers those questions in the language of Open Dungeons RPG.
