Adder Stone Games, based in Cardiff, Wales, creates the Celtic RPG, Legends of Avallen, and its epic campaign book, Against the Faerie Queene.
Against the Faerie Queene
Against the Faerie Queene is an epic fantasy campaign book full of Celtic mythology and new character options for heroes of levels 3-10 in Legends of Avallen or 5th Edition.
Be swept across the Celtic-Roman inspired clanlands of Avallen in a branching, fifteen-part adventure where the fate of both mortals and the divine hang in the balance. Your heroes will slay beasts in a mythical hunt, embroil themselves in royal politics, strategise daring heists, encounter unthinkable horrors, and finally stand against the Faerie Queene in a dungeon delve where her dark ambitions come to fruition.
Legends of Avallen
Inspired by Celtic mythology in Roman Britain, Legends of Avallen is a roleplaying game that takes you to a mystical island occupied by faithless invaders. For now, peace has been called but it balances on a sword’s edge as all seek to tame the Otherworld—a parallel realm home to fae, demons, dragons, and gods.
On Avallen, the greatest legends rise from humble beginnings, and yours will be no different. The shepherd ordained as a Druid, the bard reborn as a Fae Touched, the thief who found glory as a Gladiator. What tales will be told of you? Will you mend the rifts between worlds, or delve into their depths for fame, fortune, and power?
Legends of Avallen is a complete tabletop roleplaying game in one incredibly illustrated 244-page book.

Against the Faerie Queene - Art Book
“The King gathered a mighty army together and went his way into the province of Cornwall and set fire to the cities and castles therein. When they met face to face in battle, Gorlois was amongst the first that were slain, and all his companies were scattered. The King was sore grieved at the death of Gorlois, yet could he not but be glad that Igerne was released from the bond of matrimony. Thereafter were they linked together in no little mutual love, and two children were born unto them, a son and a daughter, whereof the son was named Arthur and the daughter Anna.”

Against the Faerie Queene - Campaign Book
With blooms and blood, oft the young Gods paid
Her sown red fields of blade and hilt
Yet when victor’s wreath might’ve been laid
Cowards’ truce harrowed all She tilledAgainst the gaze of the Faerie Queene
Avallen’s hearts will love or wilt
And Gods shall die in Annwfyn
Against the gaze of the Faerie Queene
