Tainted Grail: The Fall of Avalon is an open-world adventure RPG developed by Questline.
Alongside its main story quest, the game offers a diverse selection of side quests for players to explore.
Brotherly Love is one of the side quests in Tainted Grail: The Fall of Avalon, discovered while exploring the area.
Starting The “Brotherly Love” Side Quest In Tainted Grail
To start the quest, players must first enter the Haunted Well, located in Cuanacht, the game’s second region.

Proceed deeper into the cave until you encounter a Nuckelavee. Defeat it and loot its body. Among the various items, players will find an Ornate Belt Buckle. Picking it up instantly starts the Brotherly Love quest.

The mission objective reads: “I found a belt buckle on the corpse of a Wyrdbeast in an old well. Perhaps someone in the area knows its story.”
Talking With Rob In the Farmlands
With the Belt Buckle in hand, travel to the Farmlands and speak with Rob, who can be found inside Rob and Gill’s Cottage.

Interacting with him will start a conversation, during which you should ask about his grandfather. He will tell you about a belt buckle his grandfather owned when you show him the Ornate Belt Buckle.
After the conversation, the quest objective updates, instructing players to return later to see how things unfold.

Players can rest at a bonfire to fast-forward time or wait and return after two to three in-game days. This unlocks a new dialogue option with Rob, select it to ask about the night his grandfather died.

He’ll tell you he doesn’t remember much of that day, as he passed out after his grandfather beat him.
Furthermore, when he woke up, his grandfather was gone, and Gill had helped him patch up while acting as if nothing had happened. During the process, select the corresponding dialogue option to ask Rob if Gill still wants to stay on the farm.

He tells us that he is going to speak with Yvain’s Master of Horses to seek an apprenticeship. You can complete the conversation to conclude the Brotherly Love side quest in Tainted Grail: The Fall of Avalon.
