I've done everything of the main story up until getting the 5th clue after talking to the dragon statue close to the cat, totem and maxos runes, but now i am completely stuck and have no idea where to go. I am supposed to somehow use the clues i've gathered to open the catacombs to get to Berhlihn. I've found a Blue Orb in the Champion Academy that seems to be some kind of quest item, but its floating 20 feet in the air and i can't reach it. I've also found 3 pressure plates in a room in the Academy, i can step on 2 of them and they will start glowing (sort of) and their is a short cutscene, but if i step on the third they all stop glowing and nothing happens. Behrlihn's comments on the different clues just seems to be relating to people i can't reach because i can't get out of the damn city because a f-ing flying fortress blew the damn bridge!

So, anyone know what i should do after getting all 5 clues?
