A Battle For The Ages At Mont Crane Castle

Prepare for a protracted fight with a large number of bandits as you close in on this windswept castle at the summit of Mont Crane.

Once you have the leisure time to inspect Mont Crane Castle a little more meticulously, after all bandits that pose an immediate threat to you are neutralized, look around the lower courtyard, to a section of ruined wall in the northwest corner. Use the Eye of Nehaleni to remove the illusion; this is actually a cracked entrance into the lower dungeon of the castle itself!

Descend down the stairs, turn right, and ignore the corridor immediately to your right (southeast). Instead, follow the perimeter passageway forward (northeast), and then turn right; just before the last right turn which is a dead-end. Continue southeast down the passage that ends in a bookcase alcove. Examine the table, which contains a useful Power crystal. Pick it up.

Head down the connecting corridor with evidence of Moreau’s laboratory desks, stills, shelves of strange liquids and a row of barrels on an inaccessible loft above you. Turn left (southeast) to face a seemingly sealed stone archway wall relief. Use your Witcher Senses to pick out a button on the right side of the relief and press it. The stone arch slides back, revealing a secret passage!

Just beyond this secret door is a small passage leading to an open chest on your left. Gather some required reading, including Moreau’s journal from here. Read the notes, which detail Moreau’s son, the Witcher Jerome, arriving at Fort Ussar in readiness for some experimentation. The notes also mention an activation crystal, which you are fortunate to have already found. Slot it into the elven bracket on the wall, then summon a blast of Aard to power it. A portal appears to your right. Enter it!
