来自出版商的介绍：

《污痕圣杯：阿瓦隆的陨落》（简称TG）是一款剧情丰富的生存与探索游戏，可供1-4人游戏，背景设置在一个融合了亚瑟王传说与凯尔特神话的凄凉世界中，透过Awaken Realms（AR）的艺术家和作家们独特而黑暗的视角进行呈现。

这座名叫阿瓦隆的岛屿绝非人类居所。它曾是传说中神秘种族的栖息之地，位于我们真实的世界以及被称为冥尘的古代力量所交织的狭缝间。尽管如此，人类雄心勃勃的国王带着他们的木船，以及麾下的骑士团终究还是来到了这里。

从肆虐远方故土的瘟疫中逃离，人类一点一点地占领了这座岛屿，在岛上竖起了相貌令人感到不祥，具有某种神秘用途的巨神柱。被人类占领后，岛上曾经的主人逐渐成为了传说。

四百年后，他们的名字甚至都未曾留下；阿瓦隆人将其直呼为“先民”。这是个残酷的时代。赤死病又一次卷土重来。巨神柱正在逐渐消亡，而没有它们的力量，岛屿自身也开始坍塌，再次坠入冥尘之中。因此，你的故乡召集了五位最为强壮且睿智的英雄，并派遣他们前往遥远的卡梅洛寻求援助。而当这些勇者启程挑战这片荒蛮之地的危险时，你只是在旁远远观望。

你并非他们的其中一员……

Description from Publisher:

Tainted Grail: the Fall of Avalon is an unforgettable, solo or cooperative adventure experience for 1-4 players. Blending Arthurian legends and Celtic mythology with a unique vision, it allows you to impact the game world in deep and meaningful ways. A deep, branching storyline allows you to tackle problems in different ways, ensuring no two games play alike. Difficult decisions or harrowing choices wait behind every corner and seemingly minor tasks may reverberate with major long-term consequences.

In a land slowly sinking into the Wyrdness and torn apart by conflict; surviving each day is a challenge on its own. Starvation, sickness, violent weather, and random incidents all conspire to end your journey. Guardian Menhirs, that ensured safe travel throughout the realm, are slowly going dark turning simple logistics into an involving puzzle. To overcome these challenges, your character develops along several conflicting lines, such as Brutality / Empathy or Practicality / Spirituality. These traits unlock a rich choice of mutually exclusive skills and lead to different deck-building strategies, making character advancement meaningful and deep.

The character you develop is going to be tested during dozens of combat and non-combat encounters. Sometimes you will need to brute force your way, but often diplomacy might be a better option. Regardless whether you fight with your strength or your wits, our unique dice-less encounter system makes resolving each conflict fun and exciting, while keeping you immersed in the game.

In Avalon, there’s a legend waiting behind every stone and every tree. All locations have their own rich stories and secrets to discover. Places and characters are often much more than they seem. As you slowly put all the pieces of the larger puzzle together, the land will always have a surprise waiting for you just around the corner. Many secrets can be discovered only after several games. Created by one of the best polish fantasy authors, Krzysztof Piskorski, the story of Tainted Grail: the Fall of Avalon aims to push the boundaries of non-linear narrative, building upon the rich experience Awaken Realms has infusing ambitious stories with excellent board game mechanics and striking visuals.
