Steel Sword: The Trial Of Witcher Kiyan Is Complete

From Est Tayiar, you can journey almost due west to the territory of Grassy Knoll (south of Novigrad city). Find the small castle perched on a hill, and watch for some bothersome bandits, who may attack from horseback (but not if you push them off their steeds using Aard).

Though there’s a blood trail leading to the cellar, and an unnaturally pale and cracked corpse at the bottom, this isn’t part of your quest (this is part of Contract: The White Lady). Instead, look for the wolf sign on the boulder to the left of the castle tower entrance. Enter the tower (burst through the door using Aard), and take the ladder down into the tower cellar. There are a few chests with valuables to loot, but the real prize is the “glittering” chest in the corner. Gather the diagram and journal, the latter of which tells you more about Witcher Kiyan’s work for Prince Adrien). This isn’t required reading, as you should now have all seven diagrams, and the quest concludes.
