The Dark Castle

The Dark Castle
You’ve gathered up enough Forgotten Relics to cast the spell. It’s time to speak to Merlin.
Within the castle you meet a very sleepy door that refuses to let you pass unless you look more like the Forgotten.
You find a disguise that does the trick and continue on your journey.
You puzzle your way past more doors, doing your best with the ingredients at hand and using a “mechanical eye.”
