Tainted Grail: The Fall Of Avalon is a dark fantasy, open world RPG full of quests, loot, choices and monsters, set on a bleak island on the verge of ruin.

King Arthur is long dead and all the myths and legends are falling. Humans living in Avalon are desperately trying to find new ways of life and things to believe in. The plague of Red Death and the spreading Wyrdness are not helping. Time is running out and multiple factions have their own plan for the future of the island…

In this realm, slowly but surely sinking into chaos, you find yourself imprisoned in a damp, underground cell. At this point, you’re nobody, but who knows - you might just be the one who brings a spark of change to this land of everlasting Autumn.

Explore a world stuck in everlasting autumn, witness falling legends and make meaningful choices woven into a complex, branching storyline.

Developer Questline Games and publisher Awaken Realms are beyond excited to announce Sanctuary of Sarras, the first full-fledged expansion for Tainted Grail: The Fall of Avalon!

A drowned secret of Avalon

For six centuries, the fate of Sarras and its rebel crew has been shrouded in myth. Now, a hidden passage reveals a path into the past. In a completely new storyline, follow the trail of Nimue and the deserters who challenged King Arthur. Piece together the truth behind their disappearance and Merlin’s horrible retribution.

Sanctuary beneath the waves

The Sanctuary of Sarras invites players into a brand-new realm shaped by the deep sea. Ancient structures rise from the ever-shifting currents, and forgotten paths pulse with the life of a submerged world. But try not to get charmed, as when you begin to explore the unknown, the true nature of Sarras starts to surface.

Ancient treasures to claim

The Sanctuary brims with around 15 hours of fresh content. Meet new characters, hear their stories, and decide whether to help them. Venture into over 20 meticulously crafted dungeons and interiors. Confront unique epic bosses and other new adversaries. Discover over 100 new pieces of equipment, from armor sets and weapons to rings, amulets, relics, spells, and more; each offering a new way to improve your character.

Progression altered

A new progression system transforms the usual journey through Avalon. The underwater enemies scale to your level, keeping every encounter tense. At the same time, sacred shrines you activate weaken foes and grant points to invest in three completely new, distinct skill trees. At any moment, choose which tree is active, reshaping your build on the fly to match your current needs.
