will this "new access" to the cavern area where the last 2 keys are only acessible after you finish the main quest of defeating the darkness (walter)? I was trying to get all of my keys before finishing the game... but even after doing the hobbnobbing quest, leaving the cavern, coming back later I still cannot get access to the lower part of the cavern... so frustrating. I am already in the 121 day as a king and I dont want to go back to the castle before finishing all of the keys, books, doors and chests! Is it possible???
