Getting the Beyond The Veil achievement in Tainted Grail: The Fall of Avalon requires a fair bit of secret hunting, but it is worthwhile for unlocking the true ending of the game. There may be spoilers ahead, so beware.

Complete All Secrets Before The Final Boss

It’s best to save the secret until you have all the artifacts, but just before you finish the game. You need to go to three hidden areas, plus unlock five tombs, where you’ll get a bunch of plot info, mostly, but in the final hidden area, you get an item that lets you choose this ending at the end game, as long as you get the information from clearing all the tombs as well. You can do the first two hidden areas in the Horns of the South and Cuanacht in any order, but the one in Forlorn Swords will be locked until you get the other two. Tombs can be done whenever you have the appropriate relics as well

Location #1

You will need to obtain Excalibur first. Once you have the weapon, head to the Archspire and enter. There will be a couple of Wyrdspirits that will undergo some dialogue leading to the true ending.

Location #2

For this location, you will need the Shield of Palamedes. After obtaining the shield, go to Cuanacht and head northeast of the Elder Wyrm, up the mountain. After some climbing, there will be a door. Head inside and listen in on some dialogue.

Location #3

Head to the Forlorn Swords region and locate The Weaver’s Sanctum, behind the waterfall. There will be a boss fight within this dungeon, so prepare for a fight. You’ll get an item called the Life Spindle, which can be used in the final choice you have to make to obtain the game’s true ending.

Tomb 1

You will need to obtain Excalibur to unlock this tomb, which is found on the island where you first start the game. After you complete the quest inside and leave, an NPC will meet you, who will give you info as you progress, and the final info needed for the ending after you clear all the tombs.

Tomb 2

The Tomb of Sir Gawain can be found in Cuanacht, near a river west of the city, after you obtain the Shield of Palamedes.

Tomb 3

The Tomb of Sir Dagonet is located in Cuanacht. To unlock it, you will also need the Shield of Palamedes.

Tomb 4

You will need the Crown artifact to unlock this tomb. It is located at the northeastern corner of Forlorn Swords.

Tomb 5

Like the other tomb in Forlorn Swords, get the Crown to unlock this location. Its located northwest of the aforementioned tomb.
