Tainted Grail: The Fall Of Avalon has a series of main and side quests that keep players hooked on the world and its lore. The very first side mission players can acquire is the Unforgettable, a tragic tale of a wife and her child. This is one of the missable contents in the game, as players cannot return to the Asylum Island after they complete the tutorial. Let's check out how players can start this mission and where they can find the husband of the deceased Katrin.
How to Respec in Tainted Grail: The Fall of Avalon
Tainted Grail: The Fall of Avalon allows players to respec their skills and attribute points with the Origin Potion, though it is incredibly rare.
How to Start the Unforgettable Quest in Tainted Grail: The Fall Of Avalon (Guard Key)
Players can only start the Unforgettable quest in Tainted Grail: The Fall Of Avalon if they pick up two letters in the Asylum tutorial area. After receiving Caradoc's help in escaping from your cell, head right and keep following the hallway till you spot a dead guard slouched over beside a desk. Loot its body to get the Guard Key, which will allow you to access the jail cell, left of the one you escaped from.
Once you arrive at the cell with a dead guard next to it, open it up with the key and loot the little box at the back of the room to get an Old Letter. It's a letter from Katrin to her husband, Erfyr. Reading the letter will add the Unforgettable quest to your log.
Once you're done, keep progressing through the prison until you spot a cell with an adult and child skeletons chained to the wall. Open up the cell with a lockpick, and grab Father Vaughan's Notes from the desk and read them. Once you're done, you can progress naturally through the Asylum and enter the Horns of the South.
Where to Find Katrin's Husband Erfyr in Unforgettable Quest
To find Katrin's husband, Erfyr, players need to travel to the second major city of Cuanacht in Tainted Grail: The Fall Of Avalon. You'll only be able to access this city after pulling out King Arthur's soul from Excalibur in the Horns of the South Keep.
After arriving in the new city, make your way to the main city, at the location marked on the map above. You'll enter Erfyr's house and spot him tending to his friend, Boer. You'll need to agree to help Boer in retrieving his heart from the Lover's Hollow, which will start the Change of Heart quest. Progress through the quest and kill a creature named Fae to retrieve Boer's heart.
Once you return to Erfyr, complete the quest and talk to him again to mention the letter from Katrin. After hearing the tragic news, he'll become emotional but gain some closure. Upon completing the Unforgettable quest in Tainted Grail: The Fall Of Avalon, players will also receive the Health Ring from Erfyr. The ring will increase the wearer's maximum health by 20.
