Unlocks: Third and fourth Keeper memories
1. Niamh Fitzgerald's Trial
The third Keeper trial. By this point the pattern is familiar, and the puzzles assume you are fluent with the full spell set rather than reaching for one solution at a time.
Fitzgerald's memory plays out as a black-and-white vision built around the tale of the Deathly Hallows — the Cloak of Invisibility, the Elder Wand and the Resurrection Stone. Disillusionment auto-casts as you move between clusters of enemies, so the trial leans on staying unseen rather than fighting through it. Finishing it is worth 260 XP and the Hallowed Hero gear piece, and it's what introduces Death Shadow enemies to the wider game.
2. Lodgok's Loyalty
Lodgok is the counterweight to Ranrok: a goblin who works with wizards rather than against them. This quest is where the game does the most to complicate its own conflict.
3. San Bakar's Trial
The fourth and final trial, on the mountain. Completing it closes the Keeper sequence and puts the Final Repository within reach.
This is the last comfortable point to go and finish anything outstanding. The endgame moves quickly once it starts.
The trial itself plays out east of Bainburgh, in the Cragcroftshire region. Partway through, subduing the 'Lord of the Shore' unlocks the Graphorn as a mount, which takes its own slot separate from your broom and flying mount. The memory that closes the trial reveals that Isidora had been experimenting on Hogwarts students — the reason the four Keepers confronted her, in the battle that ultimately killed her.
Before pushing on, sweep up what you have left: Merlin Trials for gear slots, Astronomy Tables, and any companion quest still open. Everything stays available afterwards, but the finale is more satisfying at full strength.
